Force and Acceleration

  • #1
A shot putter launches a 7.260 kg shot by pushing it along a straight line of length 1.650 m and at an angle of 34.1 degrees from the the horizontal, accelerating the shot to the launch speed from its initial speed of 2.5 m/s (which is due to the athletes preliminary motion). The shot leaves the hand at a height of 2.110 m and at an angle of 34.1 degrees, and it lands at a horizontal distance of 15.90 m.

What is the magnitude of the average force on the shot during the acceleration phase?
