Abody of mass 8 kg moves in the xy-plane in a counterclockwise circular path of radius 7 meters centered at the origin, making one revolution every 5 seconds. at the time t=0, the body is at the rightmost point of the circle. a. compute the centripetal force acting on the body at time t.

Explanation:

The equation for centripetal force is given by Newton's 2nd Law:

The equation for centripetal acceleration is

If the object makes one revolution (an angle of ) every 5 seconds it means that its angular velocity is .

Putting all together, and for our values:

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.
