A car traveling at 35 mi/h crashes into a tree. The front end of the car compresses and the driver comes to rest after traveling 0.75 m. What was the magnitude of the average acceleration of the driver during the collision? Express your answer in terms of gs, where 1g 9.80 m/s. Determine the time interval of the collision, in milliseconds. 6. The tower of Pisa is 54.5 m tall. Assuming that Galileo dropped his object from rest from the top of the tower and that the effects of air resistance were negligible, how long would it take the object to fall, in seconds? What is the velocity of the object when it hits the ground? . A ball is thrown directly downward with an initial speed of 9.50 m/s from a height of 30.0m. After what time interval does the ball strike the ground? What is its velocity as it reaches the ground?
