2 cars start from the same spot with velocity u1

2 cars start from the same spot with velocity u1 and u2 . the 1st car’s @ is 2ms-2 and it runs for 8s . the 2nd one has 9.5ms-2 @ and runs for 4s . the distance they ran in the above @ and t is the same . prove mathematically that u2 is […]

with the idea of conservation of momentum explain

with the idea of conservation of momentum explain why a golf ball leaves the surface of a golf club at a much greater velocity that the club was moving before it hit the ball?

A device known as Atwood’s machine consists of t

A device known as Atwood’s machine consists of two masses hanging from the ends of a vertical rope that passes over a pulley. Assume the rope and pulley are massless and there is no friction in the pulley. Mass mB is greater than mass mA. Find expressions for the magnitude of their acceleration, a, and […]
