The velocity 2 s after throwing the object
WebMar 11, 2015 · The act of throwing a ball upward can be studied in two stages. Stage 1: When you throw a ball up you apply a force to the ball in the upward direction as long as it is in contact with your hand. This force does some amount of work on the ball. This work done is manifest as the sum of kinetic energy and potential energy of the ball. WebNov 27, 2016 · Given s ( t) = 32 + 112 t − 16 t 2 then v ( t), being the derivative of s ( t), is v ( t) = 112 − 32 t. If v ( t) = 0 then t = 7 / 2. Now, s ( 7 / 2) = 32 + 56 ⋅ 7 − 4 ⋅ 49 = 228. To find the velocity at impact solve for s ( t) = 0. This yields 16 t 2 − 112 t − 32 = 0, or t 2 − 7 t − 2 = 0. Solving this equation leads to the two possible values
