Question

A crane lifts a block of mass 260 kg vertically at an acceleration of 8.5 m/s^2 through a height of 1.6 m. What is the net force on the block?

science physics

Answer 1

Answer #1

Here, for the net force on the block

Using second law of motion

net force on the block = mass * acceleration

net force on the block = 260 * 8.6

net force on the block = 2150 N

the net force on the block is 2150 N
