Object A has a mass of 50 kg and is initially moving along the x-axis at 5.0 m/s. It collides with object B, which has a mass of 22 kg initially at rest. After the collision, object A moves with a velocity of 3.0 m/s in a direction that is 30 degrees above the x-axis. What is the final velocity (magnitude and direction) of object B?
12. -2 points SerCP1162 PU28 My Two objects of masses m,-0.52 kg and m2-0.98 kg are placed on a horizontal frictionless surface and a compressed spring of force constant 290 N/m is placed between them as in figure (a). Neglect the mass of the spring. The spring is not attached to either object and is compressed a distance of 9.2 cm. If the objects are released from rest, find the final velocity of each object as shown in figure (b)....
An object (A) of mass m A = 29.0 kg is moving in a direction that makes angle of 40° north of east with a speed v A = 5.10 m/s, while object (B) of mass m B = 17.5 kg is moving due north with a speed v B = 7.85 m/s.

Two objects collide head-on (see figure below). The first object is moving with an initial speed of 7.99 m/s to the right and the second object is moving with an initial speed of 10.00 m/s to the left. Assuming the collision is elastic, m1 = 5.12 kg and m2 = 6.15 kg,determine the final velocity of each object. (Indicate the direction with the sign of your answer. Positive is to the right, and negative is to the left.) v1f =...
