A stuntman is being pulled along a rough road at a constant velocity by a cable attached to a moving truck. The cable is paralle
1 answer:
Answer:
715 N
Explanation:
Since the system is moving at a constant velocity, the net force must be 0. The tension on the road is equal and opposite direction with the kinetic friction force created by the road and the stuntman.
Let g = 9.8 m/s2
Gravity and equalized normal force is:
N = P = mg = 107*9.8 = 1048.6 N
Kinetic friction force and equalized tension force on the rope is

Answer:
Explanation:
Velocity can be found using the following formula:
where p is the momentum and m is the mass.
The woman has a mass of 55 kilograms and a momentum of 200 kilogram meters per second.
Substitute the values into the formula.
Divide. Note that the kilograms, or kg, will cancel each other out.
The woman's velocity is 3.63636364 meters per second.
