8.4 Car #1 is going 50 mi/h when it crashes into a stationary wall and comes to a halt. An identical car # 2 is going 50 mi/h when it crashes head-on into, and sticks to, identical car # 3 going 50 mi/h in the opposite direction. Which statement is correct? A. Car #1 loses more momentum and more kinetic energy in its collision than does car # 2. B. Car #1 loses more momentum, but the...

A car that weighs 1.4×104 N is initially moving at a speed of 50 km/h when the brakes are applied and the car is brought to a stop in 15 m. Assuming that the force that stops the car is constant, find the magnitude of that force. Incorrect. Tries 5/20 Previous Tries Find the time required for the change in speed. Tries 0/20 If the initial speed is, instead, twice as great, and the car experiences the same force during...

A remote control car of mass 2,000 grams turns about a corner on a racetrack. While making the turn, it experiences a centripetal force of 0.9 N. If the toy car is traveling around the corner at a speed of 3.0 m/s, (a) what is the centripetal acceleration of the car? (b) What is the radius that the car turns about?

A driver coasts down a hill 200 m high with initial speed vo 35 m/s. The road has friction that results in a negative work -1.7 x 10° J. The effect of this is that the total initial energy is reduced by this amount by the time the car reaches the bottom of the hill. Calculate the speed of the car when it reaches the bottom of the hill. The mass of driver and passenger is 1750 kg 59.3 m/s...

Chapter 5 Q:6
A car that weighs 1.2 x 104 N is initially moving at a speed of 37 km/h when the brakes are applied and the car is brought to a stop in 20 m. Assuming that the force that stops the car is constant, find (a) the magnitude of that force and (b) the time required for the change in speed. If the initial speed is doubled, and the car experiences the same force during the braking, by...

7) A 21-ton (42,000-lb) truck collides with an 2300-lb car and causes a lot of damage to the car. During the collision A) the force on the truck due to the collision is greater than the force on the car, and the truck experiences greater acceleration. B) the force on the truck due to the collision is greater than the force on the car, and the car experiences greater acceleration. C) the forces on the truck and car are equal,...

2. In the figure, a stunt car driver negotiates the frictionless track shown in such a way that the car is barely in contact with the track at the top of the loop. The radius of the track is 9.9 m and the mass of the car is 1800 kg. Find the magnitude of the force of the car on the track when the car is at point A. You can treat the car as a...

A set of crash tests consists of running a test car moving at a speed of 12.2 m/s (27.3 mi/hr) into a solid wall. Strapped securely in an advanced seat belt system, a 71.0 kg (157 lbs) dummy is found to move a distance of 0.810 m from the moment the car touches the wall to the time the car is stopped. Calculate the size of the average force which acts on the dummy during that time. (a) Using the...
