A bowling ball of mass 4.5 kg is rolling at a constant speed of 1.35 m/s. It rolls at this speed for 3.20 s and for a distance of 4.32 m. What is the net force acting on the bowling ball during this time? Give your answer in newtons.
A blue car with mass mc = 481 kg is moving east with a speed of vc = 23 m/s and collides with a purple truck with mass mt = 1289 kg that is moving south with a speed of vt = 10 m/s . The two collide and lock together after the collision. *What is the magnitude of the initial momentum of the car? *What is the magnitude of the initial momentum of the truck? *What is the magnitude...
A car with a mass of 980 kg is initially traveling east toward an intersection with a speed of vc = 20.9 m/s and a 1500 kg pickup is traveling north toward the same intersection. The car and truck collide at the intersection and stick together. After the collision, the wreckage (car and truck) moves off in a direction of 44.0° above the x-axis. Determine the initial speed of the truck and the final speed of the wreckage in meters...
Which has more momentum? A car of mass 900 kg traveling at 30 m/s A railroad car of mass 20000 kg traveling at 3 m/s A truck of mass 1000 kg traveling at 20 m/s A bullet of mass 0.2 kg traveling at 300 m/s
A 1200·kg car traveling with a velocity of 12·m/s north collides head-on with a 2400·kg truck traveling with a velocity of 8·m/s south. Immediately after the collision, the velocity of the car is 4·m/s south. Take north as the positive direction (a) What is the velocity of the truck immediately after the collision? (b) What impluse is delivered to the car by the truck? (c) What impluse is delivered to the truck by the car?
