Answer:
65 N
Explanation:
Assuming that the ball was at rest hence initial momentum = 0
Final momentum = mv = 1Kg × 13 ms-1 = 13 kgms-1
But
Ft= mv according to Newton's law
F= mv/t
F= 13kgms-1/0.2s
F= 65 N
Answer:
τ=9.2 N.m
Explanation:
The component that contributes to torque is the y-component of the force F, so:
τ = r x F = (0.23 m) * (40 N) = 9.2m
Expressed as a vector equation:
τ = [0.23,0] x [ -31, 40] = [0, 0, 9.2] N.m
