Jamieson is competing in his school’s 3.0-metre diving competition. For his last dive, he is performing a forward somersault. The duration of the dive must be exactly 1.75 seconds or he will under- or over-rotate before hitting the water. He jumps upwards off the board with a vertical velocity of 6.0 m s−1 and takes $t$t​ seconds to land in the pool. Take the upwards direction as positive.Which of the following correctly describes the displacement of the diver as he hits the water?A0 mB3.0 mC−3.0 mD6.0 m

A baseball thrown from the outfield is released from shoulder height at an initial velocity of 28.1 m/s at an initial angle of 30.0° with respect to the horizontal. If it is in its trajectory for a total of 3.00 s before being caught by the third baseman at an equal shoulder-height level, what is the ball's net vertical displacement during its 3-s trajectory?​Select one:a.10.1 mb.​20.1 mc.zerod.9.80 me.73 m

A 73-kg swimmer dives horizontally off a 500-kg raft. The diver's speed immediately after leaving the raft is 5.0 m/s. A micro-sensor system attached to the edge of the raft measures the time interval during which the diver applies an impulse to the raft just prior to leaving the raft surface. If the time interval is read as 0.20 s, what is the magnitude of the average horizontal force by diver on the raft?Select one:a.365 Nb.1,825 Nc.73 Nd.2,500 Ne.​25 N

(08.02 MC)The function f(x) = −x2 − 9x + 10 shows the relationship between the vertical distance of a diver from a pool's surface f(x), in feet, and the horizontal distance x, in feet, of a diver from the diving board. What is a zero of f(x), and what does it represent?Group of answer choicesx = 1; the diver jumps in the pool at 1 foot per secondx = 10; the diver jumps in the pool at 10 feet per secondx = 1; the diver hits the water 1 foot away horizontally from the boardx = 10; the diver hits the water 10 feet away horizontally from the board
