Imagine this, you hear an ambulance, The ambulance is about a mile off and it isn't very loud. As it gets closer it gets louder and louder when it passes you it gets loudest then it is very quiet. So yes, your hypothesis was correct.
Answer:
3.82 Ns
Explanation:
Time varying horizontal Force is given as
F(t) = A t⁴ + B t²
F(t) = 4.50 t⁴ + 8.75 t²
Impulse imparted is given as
Answer:
Velocity
V = Q + 3Rt²
at t = 0, = Q + 3r(0) ==> Q
at t = T, = Q + 3rT²
Work done (W) = ΔKE =
W =
W = [Q² + 9R²T⁴ + 2Q(3RT²) - Q²]
W = (9R²T⁴ + 6QRT²)
