Question 1You are in an ordinary room (both its floor and ceiling are horizontal). You throw a ball directly upward and it bounces off the ceiling. While the ball is touching the ceiling, in which direction is the ceiling's support force on the ball?1 pointThe ceiling's support force on the ball is directed downward.The ceiling's support force on the ball is directed upward.The ceiling's support force on the ball is directed downward while the ball is moving upward and is directed upward while the ball is moving downward.The ceiling's support force on the ball is directed upward while the ball is moving upward and is directed downward while the ball is moving downward

4.Question 4As a ball bounces on the floor, the floor exerts an upward support force on the ball. Can the amount of that upward support force on the ball be different from the ball's weight?1 pointYes. It can be greater than the ball's weight and it can be less than the ball's weight.Yes. It can be greater than the ball's weight. It cannot be less than the ball's weight.Yes. It can be less than the ball's weight. It cannot be greater than the ball's weight.No. It can only be equal in amount to the ball's weight.

You are playing basketball and take a shot toward the basket. When the ball is midway to the basket and nothing is touching the ball, what is the direction of the net force on the basketball? [Neglect any effects due to air]1 pointDownward.Toward the basket.Toward a point slightly above the basket.Toward a point slightly below the basket.

8Jeremy throws his ball up in the air, but the ball falls back to the ground. What force made the ball move without ever touching the ball? A. the air pressure pushing on the ball B. magnetism pulling on the ball C. Jeremy's hand pushing on the ball D. gravity pulling on the ball

Two forces are acting on an object: a force to the right of 100 N, and a force to the left of 50 N.  State the magnitude and direction of the resultant force which is acting on the object.50 N to the left150 N to the right50 N to the right150 N to the left2A ball which weighs 2 N is dropped from rest.  At a given point in time, as it falls through the air, the upwards force of air resistance which is acting on the ball is equal to 0.5 N.  State the magnitude and direction of the resultant force which is acting on the ball at this point in time.  In answering this question, you may assume that no additional forces are acting on the ball.0.5 N upwards1.5 N downwards2 N downwards1.5 N upwards3In a tug-o-war competition, Team A pull with a force of 900 N, and Team B, with a force of 1.1 kN.  State the magnitude and direction of the resultant of these forces.200 N in the direction of Team A898.9 N in the direction of Team A898.9 N in the direction of Team B200 N in the direction of Team B4A car is free-wheeling down a hill at constant velocity, which means that the resultant force which is acting on it is zero.  The downhill component of its weight is equal to 10 kN, and the force of air resistance which is acting is equal to 6 kN.  Calculate the total frictional force which is acting on the car.  You may assume that no additional forces are acting on it.10 kN16 kN4 kN6 kN5Pauline is pulling a wheeled suitcase through an airport with a force of 200 N which is acting at an angle of 30° to the horizontal.  What will the horizontal component of this force be?Greater than 200 NEqual to 200 NIt is impossible to sayLess than 200 N6The three forces which are acting on an object are in equilibrium with one another.  A student draws a vector diagram to represent these forces.  In it, she connects the vectors so that they are pointing nose-to-tail.  What will this vector diagram look like?An open triangle (one in which the ends of two of the lines do not meet)A line which is made up of three vectors of equal lengthA rectangle which is missing one sideA closed triangle

You're interested in using mechanical energy to explore the motion of a ball you throw up in the air. Where do you need to put the origin of your y-axis? At the ground. Where the ball left your hand. At the ceiling. You're allowed to choose any origin you want.
