Question

ball is thrown vertically upwards with velocity 10 metre per second from the trolley moving horizontally with velocity it in metre per second person standing on ground observes its motion the range of observed by him is gravity is 10 metre per second square​

Answer 1

ANSWER:-

The trolley is moving horizontally with a constant velocity (v).

And a ball is thrown upward at the rate of 10m/s from the trolley.

To get the range of the ball w.r.t second person standing on the ground ,

Range = (velocity of body in horizontal direction)×(time of flight)

So, R =(v)(2vsin90°/10)

R = 2v/10

R =(v/5) meter.

therefore, range = (v/10) meter.
