Answer:
F = 479.21 N
Explanation:
given,
initial velocity = 0 m/s
final velocity = 16.7 m/s
time taken = 20.7 s
combined mass of the boat and trailer = 594 kg
tension in the hitch = ?
using equation of motion
v = u + a t
16.7 = 0 + a × 20.7
a = 0.807 m/s²
Force = mass × acceleration
F = 594 × 0.807
F = 479.21 N
Hence, the tension in the hitch that connects the trailer to the car is F = 479.21 N
The acceleration experienced by the particle is given by

This corresponds to the centripetal acceleration of the motion, which is related to the angular speed

of the particle and its distance r from the axis by the relationship

In our problem,

, so we can solve for

:

However, we must convert it into rpm (revolution per minute).
We know that 1 rad corresponds to

revolutions, while

. So we the conversion is
