In the adjacent figure there is a cube having a smooth groove at an inclination of 30° with horizontal in its vertical face. A cylinder A of mass 2kg can slide freely inside the grove. The cube is moving with constant horizontal acceleration A0 parallel to the shown face, so that the slider does not have acceleration along horizontal.

A cube is placed on an inclined plane of inclination  θ as shown in the figure. Coefficient of friction between the cube and the plane is  μ. As the angle  θ is gradually increased, the cube slides before toppling if

An object of mass 2 kg is sliding with a constant velocity of 4 m/s on a frictionless horizontal table. The force required to keep the object moving with the same velocity is c. 2 N a. 32 N b. ON d. 8 N

An object is sliding down a frictionless slope of 20o. The acceleration of the object (in m/s2) isGroup of answer choices3.564.90Acceleration cannot be determined because mass of the object is not known3.359.21

A block with mass m1 = 0.400 kg is released from rest on a frictionless track at a distance h1 = 3.00 m above the top of a table. It then collides elastically with an object having mass m2 = 0.800 kg that is initially at rest on the table, as shown in the figure below.A curved wedge rests on a table. The wedge has the appearance of a hill sliced vertically in half: the surface at the top is horizontal, and then it gradually increases the magnitude of its slope down to the right before turning sharply down, and then decreasing the magnitude of its slope until it is almost horizontal. The vertical distance between the surface of the table and the top of the wedge is h1. The height of the table is h2. A block labeled m1 rests on the top of the wedge. A block labeled m2 rests at the very bottom of the slope of the wedge, at the edge of the table. A dashed parabolic line shows the path m2 would take after being knocked off the table. The path ends a horizontal distance x from the edge of the table.(a) Determine the velocities of the two objects just after the collision. (Assume the positive direction is to the right. Indicate the direction with the signs of your answers.)v1 = m/sv2 = m/s(b) How high up the track does the 0.400-kg object travel back after the collision? m(c) How far away from the bottom of the table does the 0.800-kg object land, given that the height of the table is h2 = 1.95 m? m(d) How far away from the bottom of the table does the 0.400-kg object eventually land? m

A small block slides with velocity 0.5√gr on the horizontal frictionless surface as shown in the Figure. The block leaves the surface at point C. The angle θ in the Figure is:
