Question

a particle is thrown up vertically wiyh a velocity of 50metre per second. what will be it's velocity at the highest point of the journey? how high would the particle rise? what time would it take to reach highest point ​

Answer 1

the velocity at the highest point will be 0

I can answer this only

Answer 2

It's velocity at the highest point is zero because the ball's speed decreases as it goes up.

For height use v2= u2+2gh were g is negative..

For time use v= u+gt were g is negative again,u is 50m/s the initial speed and v is zero the final speed
