(a) A car accelerates from rest at 1 ms² for 20 s along a straight road. It then moves at a constant speed for half an hour. It then comes to a stop in 30s. Find the total distance covered by the car. (b) Amina throws the ball straight upward and after 1 second it reaches its maximum height then it does free fall motion which takes 2 seconds. Calculate the maximum height and the velocity of the ball when it reaches the same level on its way down. (take g =10m/s")

A engineer was accidentally thrown(downwards) overboard at an initial velocity of 6m.sand was in complete free fall. Assuming from the railing to the surface of the water is 30m. howmany seconds does it take before he hits the water?
A runner is moving with a speed of 2.68[m/s]. How long will it take the runner to complete a 5.0[km] race? Express your answer in seconds. Ignore the time it takes to reach this speed, and assume the runner is always at this speed.
In World War II, there were several reported cases ofairmen who jumped from their flaming airplanes with noparachute to escape certain death. Some fell about 20,000feet (6000 m), and some of them survived, with few lifethreatening injuries. For these lucky pilots, the tree branchesand snow drifts on the ground allowed their deceleration to berelatively small. If we assume that a pilot’s speed upon impactwas 123 mph (54 m/s), then what was his deceleration?Assume that the trees and snow stopped him over a distanceof 3.0 m.
