Question on: WAEC Physics - 2015
A body of mass 1000kg is released from a height of 10m above the ground. Determine its kinetic energy just before it strikes the ground .[g = 10ms-2]
A
10J
B
103J
C
104J
D
105J
Ask EduPadi AI for a detailed answer
Correct Option: D
Ke = mgh
Ke = Pe
\(\frac{1}{2}\)MV2 = mgh
Ke = 1000 x 10 x 10
Ke = 100000J
Ke = 105J
Ke = Pe
\(\frac{1}{2}\)MV2 = mgh
Ke = 1000 x 10 x 10
Ke = 100000J
Ke = 105J
