1)A driver is driving at 69 mi/hr on a straight highway. He sees an accident on the road in front of him, so he slams on the brakes. The car decelerates at 0.30 g. How far will the car travel before stopping? Express the answer in feet.2)A runner of mass 64.7 kg starts from rest and accelerates with a constant acceleration of 1.15 m/s2 until she reaches a velocity of 7.30 m/s. She then continues running with this constant velocity. How long does the runner take to run 129 m? 3)The minimum distance necessary for a car to brake to a stop from a speed of 100.0 km/h is 40 m on a dry pavement. What is the minimum distance necessary for this car to brake to a stop from a speed of 145.0 km/h on dry pavement? 4)A girl is standing at the edge of a cliff 201 m above the ground. She reaches out over the edge of the cliff and throws a rock straight upward with a speed of 6.17 m/s. a)How long does it take the rock to hit the ground? b)What is the speed of the rock the instant before it hits the ground?5)You are trying to improve your shooting skills by shooting at a can on top of a fence post. You miss the can, and the bullet, moving at 205 m/s, is embedded 1.53 cm into the post when it comes to a stop. If constant acceleration is assumed, how long does it take for the bullet to stop?5)A race car on a drag strip goes from 0 to 90 mph in 7 seconds. How far does it travel during that 7 seconds? Express the answer in feet.6)A particle moves on the x axis. At time t = 0 the position is x = 1 m and the velocity is v = 2 m/s. For t > 0 it has acceleration a = 3 m/s/s. At what time will it pass the point x = 22 m?
