Ek=8J
m=100g
V=?

How much is V going to be?
Explain step by step, please

Explanation:

If Ek is the kinetic energy and m is the mass and v is the velocity then v can be calculated as follows

Ek= 1/2 ×( m × v² )

2Ek= mv²

2Ek/m = v²

v =√(2Ek/m)

m = 0.1 kg

v= √(2x8/0.1)= 12.65 m/s

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).

okay i have so many questions. but the big one here is: um wt..f is this mess? ?
