Answer:
<em>The tension force of the cable is 588 N</em>
Explanation:
<u>Net Force</u>
The Second Newton's law establishes that the acceleration an object has depends on the net force through the equation:
F = m.a
If the net force is zero, then the acceleration is zero, and the object's velocity remains constant.
The crane lifts a 60 Kg load at a constant velocity. It means the net force acting on the load is zero.
There are two forces acting on the load: The weight of the load and the tension of the cable that holds it.
Since the net force is zero, both forces have the same magnitude:
T=588 N
The tension force of the cable is 588 N
The position of John at time of 4.35 s is -1.13 m
From the given chart;
- at time, t = 0, the initial velocity, u = - 2 m/s
- at time, t = 5 s, the final velocity, v = 2 m/s
The average acceleration is calculated as follows;

The position of John at time, t = 4.35 s is calculated as follows;
Thus, the position of John at time of 4.35 s is -1.13 m

if i remember correctly, to get acceleration, you subtract the initial velocity from the final velocity and divide it by the time.
if you do that (11-7) / 3, it gives you 4/3 m/s^2
