Hi.(adsbygoogle = window.adsbygoogle || []).push({});

Could someone please help me with the following M1 level Maths question. I would really appreciate any help as I am pretty stuck at the moment.

A stone is catapulted vertically upwards with a velocity of 25 m/s from a point 2 m above the ground. Find (a) its velocity when it hits the ground (b) the time it takes the reach the ground.

I took the upwards direction to be positive.

u = 25

a = -9.8

v = ?

I did not know where to go from there.

Thank you.

Cathy
