Question

If an object has a kinetic energy of 30 J and a mass of 34 kg , how fast is the object moving?

Answer 1

formulla=1/2mv^2

given:-k.e=30j

M=34kg

30=1/2*34*v^2

50=34v^2

50/34=v^2

25/17=v^2

5/underadical17

Answer 2

Answer:

0.32

Explanation:

ke = 1/2mv^2

30 = 1/2 34v^2

30 = 17v^2

v^2 = 30/17

v = sqrt 30/17

v = 0.32
