A 0.145-kg baseball pitched horizontally at 35.0 m/s strikes a bat and is popped straight up to a height of 40.0m. If the contac
Nookie1986 [14]

Answer:

F = 2.6 \times 10^3 N

Explanation:

Maximum height reached by the ball after being popped by the bat is given as

y = 40 m

now we know by energy conservation final speed of the ball after being hit by the bat is given as

\frac{1}{2}mv^2 = mgh

v = \sqrt{2gh}

v = \sqrt{2(9.81)(40)}

v = 28 m/s

now the change in momentum of the ball is given as

\Delta P = m(v_f - v_i)

\Delta P = 0.145(28\hat j + 35 \hat i)

now force is given as rate of change in momentum

F = \frac{\Delta P}{\Delta t}

F = \frac{0.145(28\hat j + 35 \hat i)}{2.5 \times 10^{-3}}

F = (1.62 \hat j + 2.03 \hat i)\times 10^3 N

so magnitude of the force is given as

F = \sqrt{1.62^2 + 2.03^2} \times 10^3 N

F = 2.6 \times 10^3 N
