For the trailer hitch in problem 3-4, determine the horizontal force that will result on the ball from accelerating a 2000-kg trailer to 60 m/s in 20 seconds. Assume a constant acceleration.

A. 6000 N
B. 12000 N
C. 24000 N
D. 60000 N

Answer :

Final answer:

The horizontal force resulting from accelerating the trailer is 6000 N. The correct option is D.

Explanation:

Given: Mass of the trailer (m) = 2000 kg, Initial velocity (u) = 0 m/s, Final velocity (v) = 60 m/s, Time taken (t) = 20 s

Using the kinematic equation:

v = u + at

60 = 0 + a(20)

a = 3 m/s^2

Horizontal force (F) = ma = 2000*3 = 6000 N

Therefore, the horizontal force resulting on the ball from accelerating the trailer is 6000 N.
