3. An 82 kg car moving east at 5.6 m/s was hit by a truck which causes it to change the direction of its motion west ward at a velocity of 2.5 m/s. (20 points) a. Determine the initial momentum of the car. b. Determine the final momentum of the car. c. Determine the impulse delivered to the car.
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
A 1200-kg car rounds a circular turn of radius R, toward the right, moving at a constant speed of 10.0 m/s on a horizontal road. Its angular momentum about the center of the turn has magnitude 2.00 - 108kg. ma. a) (4p) What is the direction of the angular momentum of the car? b) (6p) What is the radius of the turn?
1. Say there is a 50 lb dog in a car traveling 40 mph. The car comes to an abrupt stop. What is the KE of the dog? 2. Now calculate the KE of a bullet with a mass of 4 grams and a speed of 1000 m/s. Calculate your final results in SI units. How do they compare? What can you conclude from this scenario?
