A car is undergoing a crash test to determine its condition following a severe accident. The vehicle (m = 710 kg) was driving at vi = 22.5 m /s when it collided with the solid wall and came to a halt. (a) Determine its momentum before and after the incident.  (b) Determine the vehicle's impulse. (c) Predict the amount of damage to the vehicle if the automobile was driving at vi = 11.0 m

A 1500 kg car accelerates from 15 m/s to 25 m/s. Calculate the impulse experienced by the car.

I. A lump of clay (m = 3.00 kg) is thrown towards a wall at speed v = 3.00 m/s. The lump sticks to the wall. (a) What kind of collision is it? Is momentum conserved during this collision? Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision. II. Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 3.00 m/s. (a) What kind of collision is it? Is momentum conserved during this collision? Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision. III. Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 2.00 m/s. (a) What kind of collision is it? Is momentum conserved during this collision? Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during…

(a) If the impulse experienced during the collision is 200 Ns, use the information in the plot to calculate the peak force experienced during the collision.  (b) Calculate the average force experienced during the collision.

A football player is preparing to punt the ball down the field. He drops the ball from rest and it falls vertically 1.0 m down ongo his foot. After he kicks it, the ball leaves the foot with a speed of 18 m/s at an angle of 51 degrees above the horizontal.   1) what is the magnitude of the impulse delivered to the ball in Kg meters per sec as he kicks it? An american football has a mass of 420 g 2) at what angle in degrees above the horizontal is the impulse delivered to the football?

A man who could only find a 75-kg blue rock nearby decides to drive a metal beach umbrella pole down into the soft sand of Galveston beach by dropping it straight down from a resting height of 2.3 meters. If the blue rock does not rebound off the pole just after contact (that means bouncing back and possibly hitting him in the head) then calculate the impulse the rock places on the umbrella pole. Assume the metal beach umbrella has a total mass of 175-kg

3. A tennis player receives a shot with the ball (0.06 kg) travelling horizontally at 50 m/s and returns the shot with the ball travelling horizontally at 40 m/s in the opposite direction. (a) What is the impulse delivered to the ball by the racquet? (b) What work does the racquet do on the ball?
