two balls A and B are thrown simultaneously vertically upwards with a speed of 20 metre per second from the ground and the downwards s from a height of 40m with the same speed and along the same line of motion at what point does the ball collide?
A ball is thrown vertically upwards with a velocity of 10 metre per second . Itreturns to the ground with a velocity of 9 metre per second . If g is 9.8 ,then the maximum height attained by the ball is nearly?
A ball is thrown vertically upwards with a velocity of 20 metre per second from the top of a multi storey building .The height of the point from where the ball is thrown is 25 m from the ground .
How high will the ball rise and how long will it be before the ball hits the ground ?
Take g = 10 m/s
I got X - X0 as 20 m . Is this the distance ball rised or is that X ?
Thank 😺 You
