Question

In the demolition of an old building, a 1,300 kg wrecking ball hits the building at 1.07 m/s2.

Calculate the amount of force at which the wrecking ball strikes the building.

The wrecking ball strikes the building with a force of
N.

Answer 1

Use Newton's second law: F = m a.

F = 1300 kg × 1.07 m/s² = 1391 N ≈ 1.39 × 10^3 N.

(Assumes the given acceleration is the ball's deceleration during impact.)
