Answer:
F = 145 N
Explanation:
Given that,
Force applied by Jeff is 85 N and the force applied by Chris is 60 N. Both forces are acting in the same direction to push a rock up a hill. It means that net force is equal to the sum of these two forces.
So,
Net force on the rock = 85 N + 60 N
= 145 N
Hence, the net force on the rock is 145 N.
Answer:
Explanation:
As we know that tension force in the string will be equal to the centripetal force on the string
so we will have
now we have
now we have
now when string length is 0.896 m and its speed is 71.5 m/s then we will have

Explanation:
To find velocity, we take the derivative of the original position equation. To find acceleration, we take the derivative of the velocity function. To determine the direction of the particle at t = 1 t=1 t=1, we plug 1 into the velocity function.
Refer to the diagram shown below.
The tension, T, in each cable is the same because of vertical symmetry.
For vertical equilibrium,
2T sin(24°) = 400 N
0.8135 T = 400
T = 491.7 N
Answer: 491.7 N
