A 2kg pumpkin is thrown with a velocity of 15m/s towards a
brick wall. The pumpkin comes to a crashing rest (0 m/s) in
0.05 seconds. What is the force exerted on the pumpkin by
the wall?

The force exerted on the pumpkin by

the wall is 600N.

HOW TO CALCULATE FORCE:

  • The force exerted by the wall on the pumpkin can be calculated by multiplying the mass of the pumpkin by the acceleration.

  • However, the acceleration of the pumpkin needs to be calculated by the following expression:

  • a = (v - u)/t

Where;

  1. a = acceleration (m/s²)
  2. v = final velocity (15m/s)
  3. u = initial velocity (0m/s)
  4. t = time (0.05s)

  • a = (15 - 0)/0.05

  • a = 15/0.05

  • a = 300m/s²

  • F = 2kg × 300m/s²

  • F = 600N

  • Therefore, the force exerted on the pumpkin by the wall is 600N.
