A 10 kg mass moving at 5 m/s collides head on with a 4 kg mass moving at 2 m/s in the same direction. If e = 1/2, find their velocity after impact.
Given: m1 = 10 kg, m2 = 4 kg u1 = 5 m/s, u2 = 2 m/s, e = \(\frac{1}{2}\) To find: Velocity after impact (v1 and v2) Formulae: i. m1u1 + m2u2 = m1v1 + m2v2 ii. e = \((\frac{v_2-v_1}{u_1-u_2})\) Calculation: From formula (i), 10 × 5...

A cricket ball of mass 150 g moving with a velocity of 12 m/s is turned back with a velocity of 20 m/s on hitting the bat.
m = 0.150 kg, v = 20 m/s, u = -12 m/s and t = 0.01 s To find: Average force (F) Formula: F = \(\frac{m(v-u)}{t}\) Calculation: From formula, F = \(\frac{0.150[20-(-12)]}{0.01}\) = 480 N The average force exerted...
