10 pts Question 6 6) A mass of 8 kg is moving at 20 m/s in the +x direction and collides in a perfect elastic collision with a 3 kg mass moving in the +x direction at 6 m/s. If the masses are in contact for 0.15 seconds, what is the average force on the 8 kg mass in Newtons? Include a negative sign if in the negative x direction.
A truck moving at 11 m/s crashes into a tree and stops in 1.02 s. The mass of the driver inside is 74 kg. Calculate the magnitude of the force, in newtons, that the seat belt exerts on the driver of the truck to bring him to a halt.
A car moving at 8.0 m/s crashes into a tree and stops in 0.24 s. Calculate the force the seat belt exerts on a passenger in the car to bring him to a halt. The mass of the passenger is 75 kg
A car is moving at a speed of 60 m/s, when the driver applies the brakes, which causes a deceleration of 2 m/s2. How many seconds will it take for the car to stop and how far will it travel till it stops? 30 sec, 450 meters 25 sec, 800 meters 30 sec, 1800 meters 20 sec, 900 meters 30 sec, 900 meters Flag this Question Question 192 pts You throw a ball downward from a height of 5 meters...
