A many Mass 90kg is moving at a constant velocity,he has kinetic energy of 2205j.calculate his velocity
Ke=1/2pmv²=j
1/2×90=45
2205÷45=49
help me
A man of mass 90 is moving at a constant velocity He has kinetic energy of 2205 calculate his velocity
I said find the workings and answer to the question
K.E = 1/2 MV²
K.E =2205
2205 = 1/2 * 90 = 45
2205 /45 = 49m/s²
K.E = 1/2 MV²
K.E = 2205
2205 = 1/2 *90 =45
2205/45 = 49
V² =49 square root
V = 7
Ke = (1/2) m v^2
so
(1/2) (90) v^2 = 2205
