A trolley of mass 300 kg carrying sandbag of 25 kg is moving uniformly with a speed of 27 km/h on a frictionless track. After a while, sand starts leaking out of a hole on the floor of the trolley at the rate of 0.05kg s^(-1). What is the speed of the trolley after the entire sand bag is empty?

1.	A trolley of mass 300 kg carrying sandbag of 25 kg is moving uniformly with a speed of 27 km/h on a frictionless track. After a while, sand starts leaking out of a hole on the floor of the trolley at the rate of 0.05kg s^(-1). What is the speed of the trolley after the entire sand bag is empty?
Answer» Solution :`=27 KMH^(-1)` (no change in SPEED)
