hey i really need urgent help and i know this is a maths forum but i think this forum is really good. Its my physics homework on suvat equations and maths is closely associated with physics
I really dont get this question
1.A particle falls freely from a rest. In the last second of its motion, it falls 5/9 of its total fall. How far did it fall?
2. A ball is dropped from a height of 20m and rebounds with a velocity which is 3/4 of the verlocity with which it hits the ground. What is the time interval between the first and second bounces?
im really stuck, thanks ellie x
