A 0.023 kg golf ball moving at 15.7 m/s crashes through the window of a house in 5.3 × 10−4 s. After the crash, the ball continues in the same direction with a speed of 11.4 m/s. Assuming the force exerted on the ball by the window was constant, what was the magnitude of this force? Answer in units of N.

Magnitude of the force exerted on the window = 186.6 N

Explanation:

Impulse = change in momentum

Impulse = force × time period during which it acts = F × t = Ft

Change in momentum = m(v₁ - v₂)

m = 0.023 kg, v₁ = 15.7 m/s, v₂ = 11.4 m/s

Change in momentum = 0.023 (15.7 - 11.4) = 0.0989 kgm/s

Impulse = change in momentum = 0.0989

Ft = 0.0989

t = 5.3 × 10⁻⁴ s = 0.00053

F = 0.0989/0.00053 = 186.6 N

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

false
