1. A 1,000 kg car moving north at 30 mph collides into a 2,000 kg truck which is also moving north, but at 10 mph. Immediately after the collision, the truck’s speed is 13 mph. What is the speed of the car after the collision? Express your answer in mph and input the number only. 2. Was kinetic energy conserved in this collision? A. Yes B. No 3. What type of collision was this? A. Perfectly inelastic B. Inelastic C....
A 1100-kg car is moving at 20 m/s due north. A 1600-kg car is moving at 19 m/s due east. The two cars simultaneously approach an icy intersection where, with no brakes or steering, they collide and stick together. Determine the speed and direction of the combined two-car wreck immediately after the collision. magnitude=? direction=?
A car moving at 25 m/s crashes into a tree and stops in 0.3 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. (Enter the magnitude.) = ________ N
A 800 kg car moving east at 31 m/s runs head-on into a 3100 kg truck moving west at 21 m/s. The vehicles stick together. Use the concept of the center-of-momentum frame to determine how much kinetic energy
What is the velocity (in m/s) of a 935 kg car initially moving at 28.0 m/s, just after it hits a 140 kg deer initially running at 10,5 m/s in the same direction? Assume the deer remains on the car. (Enter the magnitude.) m/s Additional Materials Reading
