10J
103J
104J
105J
Correct answer is D
Ke = mgh
Ke = Pe
\(\frac{1}{2}\)MV2 = mgh
Ke = 1000 x 10 x 10
Ke = 100000J
Ke = 105J
133.2g
66.0g
60.0g
22.0g
Correct answer is B
clockwise movement = anticlockwise movement
w x 10 = 22 x 30
w = \(\frac{22 \times 30}{10}\)
w = 66.0g
500.0ms-1
100.0ms-1
70.0ms-1
50.0ms-1
Correct answer is B
V2 = U2 + 2gs
V2 = 0
V2 = 2gs
h = 500m
g = 10ms-2
V2 2 x 10 x 500
V2 = 10,000
V = \(\sqrt{10000}\)
V = 100ms-1
