Question

an object of mass 2 kg moves with a velocity v has a kinetic energy of 121 J. Find its velocity​

Answer 1

Answer:

EK=½mv²

121=½(2)v²

121=v²

v=11 m/s

velocity is 11m/s

Answer 2

Answer:

V=11m/s

Explanation:

M=2kg

Kinetic = 121J

kinetic energy=1/2mv²

121=1/2×2v²

121=v²

v=√121

v=11m/s

velocity =11m/s
