Step-by-step explanation:
Given
[tex] \rm{m = 2.5 \ kg} \\ \rm{V_i = 27 \ m/s}\\ \rm{V_f = 0 \ m/s} \\ \rm{\Delta t = 1.7 \ s } [/tex]
Required
[tex] \\ \rm{ F = ?} \\ [/tex]
Equation
[tex] \\ \rm{F\Delta t = m(V_f - V_i)}\\ [/tex]
Solution
[tex] \rm{F(1.7) = 2.5(0 - 27)} \\ \rm{F(1.7) = 2.5(-27)}\\ \rm{1.7F = -67.5} \\ \rm{\frac{1.7F}{1.7} = \frac{-67.5}{1.7}} \\ \rm{F \approx -39.7N} [/tex]
Answer
[tex] \therefore [/tex] The force that execterd on the ball by the receiver is -39.7N
