500.0g
400.0g
44.4g
25.0g
Correct answer is D
clockwise moment = Anti-clock wise moment
= M x 40 = 100 x 10
M = \(\frac{1000}{40}\)
= 25g
0.25ms-2
0.80ms-2
3.20ms-2
4.00ms-2
Correct answer is B
S = ut + \(\frac{1}{2} at^2\)
40 = 0 x 10 + \(\frac{1}{2}\) x a x 102
50a = 40
a = \(\frac{40}{50}\)
= 0.8ms-2

2.00s
2.18s
3.00s
Correct answer is B
T = \(\frac{2u}{g} = \frac{2 \times 10}{10} = 2s\)
