0.36J
0.72J
360.00J
720.00J
Correct answer is A
P.E at max = K.E on projection
= \(\frac{1}{2}\)mv2 = \(\frac{1}{2} \times 0.02 \times 6^2 = 0.36J\)
1.2ms-1
6.0ms-1
12.0ms-1
0.6ms-1
Correct answer is C
V = u - gt
u = v + gt
= 0 + 10 x 1.2
= 12ms\(^{-1}\)
The total area under a force-velocity graph represents
energy
momentum
power
pressure
Correct answer is C
Power = Force x Velocity.
Therefore, the area under the force- velocity graph gives Power.
3.1ms-2
5.2ms-2
6.0ms-2
8.7ms-2
Correct answer is D
a = g sin \(\theta\)
= 10 sin 60
= 8.7 ms\(^{-2}\)
