Question

A pendulum of a given mass is pulled back through a given vertical height and released to swing back down to a 'wall' where it impacts.

Can i use mg delta h to get E kin; and then use E= half mv^2 to get the collision impact velocity?

Would someone check my thinking please? Thanks.

Answer 1

Yes, that method will work. It leads to

2g*delta h = V^2

Answer 2

Thanks very much, I appreciate it.
