Question

a ball is thrown vertically upwards from the ground with a velocity u then how high will the ball rise

Answer 1

Answer:

u²\2g

Step-by-step explanation:

initial velocity=u

final velocity (v)=0 {at max height}

Accel.=gravity=-g

let s be max height

v²-u²=2as

0²-u²=2*-g*s

s=-u²\2*-g

(cut negative sign)

s=u²\2g

please mark me as brainest

Answer 2

Answer:

a ball is thrown vertically upwards, it reaches its maximum height in 2.5 s. If the acceleration of the ball 10m/s2 be directed towards the ground.
