an object is moving along a circle of radius 400.0m with a speed of 20.0m/s. the centripetal force acting on the object is 500.0N
a) find the mass of the object
b) find the work done by the centripetal force
c) what is the angular velocity of the object

Expert Solution

a) the centripetal force = mv²/R

=> 500.0 = (m * 20.0²)/400.0

=> the mass of the object , m = 500 kg

b) work done by the centripetal force = 0 J

c) the angular velocity of the object = v/R

= 20/400

= 0.05 rad/s

An object with mass m1= 3.00 kg is moving along the positive x-axis with a speed v1i=2 m/s straight towards two objects with masses m2= 2.00 kg and m3= 4.00 kg, which are initially at rest. When they collide, object 1 comes to rest and object 2 moves away with a speed of v2f=1.5 m/s at an angle of 50o from the incoming path of object 1. For everything that follows, use a coordinate system where the final path of...

A trooper is moving due south along the freeway at a speed of 33 m/s. At time t = 0, a red car passes the trooper. The red car moves with constant velocity of 45 m/s southward. At the instant the trooper's car is passed, the trooper begins to speed up at a constant rate of 1.5 m/s2. What is the maximum distance ahead of the trooper that is reached by the red car? m
