Question 9 5 pts The automobile shown below has a weight of 2700 lbf. It is moving at 4 ft/s when it crashes into a rigid wall. If the impact occurs in 0.06 seconds, determine the average impulsive force in lbf) acting on the car during the collision.
*15-8 The automobile has a weight of 2700 lb and is traveling forward at 4 ft/s when it crashes into the wall. If the impact occurs in 0.06s, determine the average impulsive force acting on the car. Assume the brakes are not applied. If the coefficient of kinetic friction between the wheels and the pavement is He 0.3, calculate the impulsive force on the wall if the brakes were applied during the crash. The brakes are applied to all four...
A 0.25 lbf baseball is pitched with a velocity of 80 ft/s toward a batter. After the ball is hit by the bat B, it has a velocity of 120 ft/s in the direction shown. If the ball and bat are in contact for 0.015 seconds, determine the average impulsive force exerted on the ball (in lbf) during impact. 120 fts 40° B 80 ft/s

Two bumper cars collide head on. Bumper car 1 has a weight of 150 lb and is moving with a speed of 6 ft/s. Bumper car 2 has a weight of 170 lb and is moving with a speed of 4 ft/s. If no energy is lost during the collision, A) what are the velocities of the two cars after the collision? B) What is the magnitude of the average force between the two cars during the collision if it...
A 4.0-kg particle is moving horizontally with a speed of 5.0 m/s when it strikes a vertical wall. The particle rebounds with a speed of 3.0 m/s. The collision occurs in 2 ms. (a) what is the magnitude of the impulse delivered to the particle? (b) What the average impulsive force acted to the particle? Answers: (a) 24 Ns and (b) 1.6 x 104 N. Show steps and equations used.
5. An automobile of mass 1500 kg moving at 25.0 m/s collides with a mass 4500 kg at rest. The bumpers of the two vehicles lock together the crash. a. Compare the force exerted by the car on the truck with that exerted truck on the car during the collision. Is one force larger than the are they equal in magnitude to each other? b. What is the final velocity of the car and truck just after the collision? Show your calculations. 6....
The automobile has a speed of 50 ft/s at point A and an acceleration having a magnitude of a = 20 ft/s2 , acting in the direction shown. Part A) Determine the radius of curvature of the path at point A. Part B) Determine the tangential component of acceleration. θ=30°
