She throws ithorizontally at 3.00 m/s to Twin B. Neglecting any gravityeffects, what are the subsequent speeds of Twin A and Twin B?Your friend’s car has broken down, so you volunteer to push it with your own car to the nearestrepair shop, which is 2.0 km away. You carefully move your car so that the bumpers of the two carsare in contact. You then slowly accelerate to a speed of 2.5 m/s over the course of 1.0 min. The massof your friend’s car is 1.2 x 10 ^3 kg. Assume negligible friction.a) Calculate the normal force between the two bumpers. b) You then maintain a speed of 2.5 m/s. How long does it take you to reach the repair shop? c) Sketch the shape of a velocity time graph for the entire motion. d) Sketch the shape of a position time graph for the entire motion.A 94.0 kg person is riding in a car moving at 21.0 m/s when the car runs into a bridge abutment.

After the cars collied, they couple and roll together with a speed of ___ m/sA bullet of mass 3.0g moving at 350m/s hits a tree and penetrates through a distanceof 12 cm before coming to rest. Determine the retarding force exerted on the bulletA nucleus that captures a stray neutron must bring the neutronto a stop within the diameter of the nucleus by means of thestrong force. That force, which “glues” the nucleus together, is approximatelyzero outside the nucleus. Suppose that a stray neutronwith an initial speed of 1.4 * 107 m/s is just barely captured by anucleus with diameter d = 1.0 * 10-14 m. Assuming the strongforce on the neutron is constant, find the magnitude of that force.The neutron’s mass is 1.67 * 10-27 kg.
