A skydiver jumps from a plane. Ignoring the effects of air resistance, what will be the skydiver’s speed after falling for 5.50 s? Assume that the negative direction is down.   v=−59.8ms   v=−63.3ms   v=−55ms   v=−57.4ms

QUESTION 2 A ball is thrown straight up in the air. When it reaches a height that is n times smaller than the maximum height it can reach, its speed is v. Calculate the maximum height, in meters. n = 3.9 v = 16.8 m/s to saue all answers.

A car traveling form a city "A" at 22.4 m/s skids to a stop in 2.55 s, with constant acceleration. Determine the skidding distance of the car from the starting point. Select one: a = 25.5 m.s 2 a = 15.1 m.s-2 a = 28.6 m.s 2 a = 22.6 m.s?

2. An object of mass 200 g (0.2 kg) is thrown vertically upwards with a velocity of 8 m/s from a height of 10 m above the ground. It reaches certain maximum height and falls straight back to ground. Ignore air resistance in this problem. (a) Draw v-t graph that represents the velocity of the object after it is launched upwards and until it hits the ground. (b) How long does it take for the object to reach the maximum height? (c) What is the maximum height of the object from the ground? (d) How long does it take for the object to reach the ground from the highest point of motion? (e) What is the velocity of the object as it reaches ground? (Hint: Not zero).
