Perpendicular 62844

A body with a mass of 4 kg hits an obstacle at a speed of 10 m/s. After the collision, the body continued to move at a speed of 6 m/s, while the direction of this speed was perpendicular to the direction of the speed before the collision. Find:

a) change in the magnitude of the velocity and momentum of the body
b) the magnitude of the change in velocity and momentum of the body.

Correct answer:

v =  11.6619 m/s
h =  46.6476 kgm/s

Step-by-step explanation:

m=4 kg v1=10 m/s v2=6 m/s α=π/2=3.1416/21.5708  v=v12+v22=102+62=2 34=11.6619 m/s
h=m v=4 11.6619=8 34=46.6476 kgm/s
