Question

A 800. kg cannon on a frictionless horizontal surface launches a 40.0 kg cannonball with a velocity of 120. m/s horizontally to the right.

a) In which direction will the cannon move?

b) What is the recoil velocity of the cannon

science physics

Answer 1

Answer #1

canon move to the left

=====

using conservation of momentum

m1 v1 = m2 v2

800 v1 = 40* 120

v1 = 6 m/s

=====

Comment before rate in case any doubt, will reply for sure. if
