4) A ball traveling at 12 m/s, begins to roll up a ramp inclined at 55 degrees. Find the time to reach the top of the ramp and find the distance the ball has traveled up the ramp after half this time has elapsed.

5) A particle is rotating in uniform circular motion at the end of a massless rod that is 5.2 meters long. If the particles tangential speed is 22 m/s, find the number of revolutions it will complete in one hour (3600 seconds) and the centripetal acceleration.

6) For the following block find the net Force in the x and y directions (choose up and to the right as positive.) Which way does will it move? (10 points) F1: 12 N F3 =4 N 50 60 F2=9N
