- Mass C , which has a mass of 4 kg, is suspended from a cord attached to cart A , which has a mass of 5 kg and can roll freely on a frictionless horizontal track. A 60-g bullet is fired with a speed v0 = 500 m/s and gets lodged in block C . Determine (a) the velocity of C as it reaches its maximum elevation, (b) the maximum vertical distance h through which C will rise.arrow_forwardA ball is thrown from the top of a 25-m tall building with an initial velocity v 0 at an angle above the horizontal. If it strikes the horizontal ground below at a distance 20 m from the foot of thebuilding, determine v 0 and .

Knowing that the fragments hit the vertical wall at the points indicated, determine the speed of each fragment immediately after the explosion. Assume that elevation changes due to gravity may be neglected.arrow_forward
- vehicles are approaching a road junction, both moving with speed (12.5 m/s). One vehicle has mass 1000 kg and the other mass kg, and the roads meet at an angle of 60° as shown.

A second collision then occurs when B strikes A. Assuming the first collision is perfectly plastic and the second collision is perfectly elastic, determine the velocities of the three vehicles just after the second collision.arrow_forward
- Two spheres, each of mass m, can slide freely on a frictionless, horizontal surface. Sphere A is moving at a speed v0 = 16 ft/s when it strikes sphere B which is at rest, and the impact causes sphere B to break into two pieces, each of mass m/2.a) Knowing that 0.7 s after the collision one piece reaches Point C and 1.17 s after the collision the other piece reaches Point D, determine the velocity of sphere A after the collision.b) Knowing that 0.7 s after the collision one piece reaches Point C and 1.17 s after the collision the other piece reaches Point D, determine the angle θ and the speeds of the two pieces after the collision.arrow_forwardPart A Ball A has a mass of 3 kg and is moving with a velocity of (vA)ı = 8 m/s when it makes a direct collision with ball B, which has a mass of 2.5 kg and is moving with a velocity of (vB)1 = 5 m/s.
