Question

A 7 g bullet is travelling at a speed of 160 m/s towards a 650 g block which lies on a horizontal and frictionless surface at the end of a string of length 1.5 m. The bullet's trajectory is tangent to the circle defined by the string. (Figure 1)The bullet goes completely through the block and exits with a speed of one-half its initial speed.

1.)What is the velocity of the 650 g block after the bullet exits?

2.)After the collision, the 650 g block moves in a circle defined by the string. What is the tension in the string?

Please show all work and list all ansers properly at end
