Asked Oct 31, 2019

A * 60kg* sled is pulled by a string with a force of 100N and the string makes an angle of 60 degrees above the horizontal (up and to the right). The sled starts at rest and is moving at 2.5 m/s to the right after 5 seconds.

1. Find the acceleration of the sled.

1. Find the horizontal component of the pull force (Horizontal tension).

2. Using the acceleration found in part 1 and the force in part 2, find the force of friction opposing the forward motion.

Step 1

**Given:**

Mass of the sled = 60 kg

Force pulling the sled = 100 N at 60 degrees above horizontal

Velocity of sled after 5 seconds = 2.5 m/s

Step 2

(a) Calculating the acceleration of the sled:

Step 3

(b) Calculating the horizo...
