The free-body diagram of a crate is shown.
2 answers:
The net force acting on the crate is the sum of all the forces acting in the different directions on the crate, which is 176N to the left.
- Upward force = 440 N
- Downward force = - 440N
- Rightward force = 176 N
- Leftward Force = - 352N
<u>The net vertical force acting on the crate</u> :
- Upward force + Downward force
- 440N + (-440N) = 0 N
<u>The net horizontal force acting on the crate</u> :
- Rightward force + Leftward force
- 176 N + (- 352 N) = - 176N
<u>The total net force acting on the crate</u> :
- Vertical + horizontal force
- 0 + (-176 N) = - 176 N
Therefore, the net force acting on the crate is - 176 N, which is 176 N to the left.

Answer:
The average linear velocity (inches/second) of the golf club is 136.01 inches/second
Explanation:
Given;
length of the club, L = 29 inches
rotation angle, θ = 215⁰
time of motion, t = 0.8 s
The angular speed of the club is calculated as follows;
The average linear velocity (inches/second) of the golf club is calculated as;
v = ωr
v = 4.69 rad/s x 29 inches
v = 136.01 inches/second
Therefore, the average linear velocity (inches/second) of the golf club is 136.01 inches/second
