A0.311 kg tennis racket moving 30.3 m/s east makes an elastic collision with a 0.0570 kg ball moving 19.2 m/s east. Find the velocity of the tennis racket after the collision

Answer 1

Here m1 =0.311 kg, u1 = 30.3 m/s

m2 = 0.0570 kg, u2 = 19.2 m/s

v1 = Final speed of racket after collision

v2 = Final speed of ball after collision

v1 = ( 0.311- 0.0570) 30.3 /(0.311 + 0.0570) + (2*0.0570) ( 19.2/ 0.3680)

V2 = 2* 0.311*30.3/ 0.3680 +

( 0.0570 - 0.311) 19.2/)/ 0.3680

+ sign will mean East and negative will mean west
