A small sphere of mass m = 2kg moving with a velocity u=4i?7j?m/s collides with a smooth wall and returns with a velocity v?=i?3j?m/s. The magnitude of the impulse received by the ball is
Added by Anuj C.
Step 1
The initial velocity of the sphere is given as \(\mathbf{u} = 4\mathbf{i} - 7\mathbf{j}\) m/s, and the final velocity after the collision is \(\mathbf{v} = \mathbf{i} - 3\mathbf{j}\) m/s. Show more…

A 3.0-kg ball with an initial velocity of (4i + 6j) m/s collides with a wall and rebounds with a velocity of (–4i + 2j) m/s. What is the impulse exerted on the ball by the wall?

A ball (m= 0.4kg) is moving toward a wall ( V1 = 10 m/s) and after a collision, will return with V2 = 8 m/s ( Opposite direction) What is the impulse force (F) if the collision time was t = 0.001 s F = 800 N F = - 800 N F = -7200 N F = 7200 N
