During a practice shot put throw, the 7.7-kg shot left world champion C. J. Hunter's hand at speed 14 m/s. While making the throw, his hand pushed the shot a distance of 1.4 m. Assume the acceleration was constant during the throw. A) Determine the acceleration of the shot.
B) Determine the time it takes to accelerate the shot.
C) Determine the horizontal component of the force exerted on the shot by hand.

Aman throws a football straight into the air. as it rises, it slows down. which type of energy is the football gaining?

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f

Ashot putter releases the shot some distance above the level ground with a velocity of 12.0 m/s, 51.0 ∘above the horizontal. the shot hits the ground 2.08 s later. you can ignore air resistance. how far did she throw the shot?
