Question

a cart of mass 50kg is moving on a straight track with speed of 12m/s .a mass of 10kg is gently put into the cart.wht will be the velocity of the cart after this

Answer 1

Mass of cart ,   M = 50 kg and   speed of cart, V = 12m/s
Let mass m=10 kg  put into cart with speed v
According to law of conservation of momentum (newton's second law)

MV=mv
50 x 12 = (50+10) x v
v = 10 m/s

now velocity of cart after put 10 kd is 10 m/s

i hope it will help you
regards

Answer 2

Answer:

s

Explanation:

Mass of a cart,M=50kg and speed of a cart,V=12m/s

m=10kg

MV=mv

50×12=(50+10)×v

V=10m/s

Velocity of a cart after put 10kd is 10m/s
