A 1000- kg car collides with a 1300- kg car that was initially at rest at the origin of an x-y coordinate system. After the collision, the lighter car moves at 20.0 km/h in a direction of 25 o with respect to the positive x axis. The heavier car moves at 23 km/h at -41 o with respect to the positive x axis. What was the initial speed of the lighter car (in km/h)? What was the initial direction (as measured counterclockwise from the x-axis)?

(c7p50) A 900- kg car collides with a 1400- kg car that was initially at rest at the origin of an x-y coordinate system. After the collision, the lighter car moves at 30.0 km/h in a direction of 30 o with respect to the positive x axis. The heavier car moves at 33 km/h at -46 o with respect to the positive x axis. What was the initial speed of the lighter car (in km/h)? What was the initial direction...

A 1300 kg car moving at 5.4 m/s is initially traveling north in the positive y direction. After completing a 90° right-hand turn to the positive x direction in 4.1 s, the inattentive operator drives into a tree, which stops the car in 280 ms. What is the magnitude of the impulse on the car (a) due to the turn and (b) due to the collision? What is the magnitude of the average force that acts on the car (c)...

1. Ball B, moving in the positive direction of an x axis at speed v, collides with stationary ball A at the origin. Ball A and B have different masses. After the collision, B moves at an angle of +30° with respect to the x axis with half its initial speed. (a) In what direction does A move as an angle with respect to the x axis? (b) If the collision is elastic, what is the ratio of the masses...

An unstable nucleus of mass 1.7 ✕ 10−26 kg, initially at rest at the origin of a coordinate system, disintegrates into three particles. One particle, having a mass of m1 = 1.0 ✕ 10−27 kg, moves in the positive y-direction with speed v1 = 5.0 ✕ 106 m/s. Another particle, of mass m2 = 8.0 ✕ 10−27 kg, moves in the positive x-direction with speed v2 = 3.8 ✕ 106 m/s. Find the magnitude and direction of the velocity of...

A 1000-kg car approaches an intersection traveling north at 15.0 m/s. A 1300-kg car approaches the same intersection traveling in the same direction behind first car at at 28.0 m/s. The two cars collide at the intersection and lock together. Ignoring any external forces that act on the cars during the collision, what is the velocity of the cars immediately after the collision?

A 1300-kg car, initially at rest, is initially accelerated at 4.9m/s2. After the car moves 550m, the engine is cut off. The car then moves a distance of 1230 before coming to a stop. Assume the road to be level and that g = 10 N/kg. a) What is in m/s, the magnitude of the velocity of the car at the end of the first 550m? b) What is in m/s2, the magnitude of the acceleration of the car while...
