30s
20s
25s
15s
Correct answer is D
The total time of flight is given as
\(T = \frac{2usin\theta}{g}\)
Hence, time to maximum height is half of the total time of flight,
t = \(\frac{u sin\theta}{g}\)
= \(\frac{300 \text {sin} 30}{10}\) = 15s
30cm
10cm
20cm
25m
Correct answer is C
Clockwise moment = Anti-clockwise moment
10 x 30 = 15 x X
X = 20cm
300N
600N
1200N
400N
Correct answer is C
F = Ma + mg = 60 x 10 x 60 x 10 = 1200N
