Question

a girl of mass 40 kg jumps with a horizontal velocity 5 m/sec on stationary cart with friction less wheel. The mass of cart is 3 kg. What is her velocity as she moves of the cart?
Explain with figure. ​

Answer 1

hey mate here is your answer

Mass of Girl (M) = 40 Kg

Velocity of Girl (V) = 5 m/s

Mass of Cart = Mass of girl + Mass of cart = 43 Kg

=> MV = mv

=> 40 x 5 = 43 x v

=> 200/43 = v

=> v = 4.65 ms^-1
