The magnitude of the resultant force is given by the centripetal force, since the car is under a circular motion. So, we have:
The centripetal acceleration is given by:
Where v is the linear speed and r the radius of the circular motion. Replacing this and solving:
Answer:
Hello there, please see explanations for step by step answer.
Explanation:
Radius 6 ft and
Height 18 ft is filled to a height of 11 ft of a liquid weighing 64.4 lb divided by ft cubedlb/ft3.
How much work will it take to pump the contents to the rim.

Answer:
Explanation:
Given
mass of steel ball
initial speed of ball
Final speed of ball (in upward direction)
Impulse imparted is given by change in the momentum of object
therefore impulse J is given by
so magnitude of Impulse =4 N-s
Answer:
1.70 J
Explanation:
The heat dissipated is the difference in the kinetic energies.
This is given by
and
are the initial and final velocities.
With <em>m</em> = 0.175 kg,
The negative sign appears because energy is lost.
