A ball with mass 2 kg hits a wall with velicity of (5i+6.5j+4k) m/s and rebounds with a velocity of (2i+3.5j+3k) m/s. Calculate the magnitude of the impulse on this ball during this collision with the wall? 3.3N.s 11.3 N.s 8.7 N.s 5.1N.s -6N.s

Step 1
The change in velocity is given by the final velocity minus the initial velocity: Δv = (2i+3.5j+3k) - (5i+6.5j+4k) = -3i - 3j - k Show more…
