Question

A horizontal force of 0•80N is Required to pull A 5kg Block Across a table top at a constant speed. With the block initially at rest again. Determine the speed v of the bullet where the bullet is assumed to be embedded in the block.

Answer 1

$Fd=\frac{mv^2}2,$

$v=\sqrt{\frac{2Fd}m}=\sqrt{0.32d}.$
