a force acts on a body 0.5sec changing its momentum from 16.0kg to 21.0kg.calculate the magnitude of the force
assume you mean 16 and 21 kg m/s for momentum
F = change in momentum / change in time
= (21 - 16)/.5 = 10 Newtons average over the half second
To calculate the magnitude of the force, you need to use the formula for calculating the change in momentum:
Force = (change in momentum) / (change in time)
Given:
Initial momentum (p₁) = 16.0 kg
Final momentum (p₂) = 21.0 kg
Change in time (Δt) = 0.5 sec
First, find the change in momentum:
Change in momentum = p₂ - p₁
Substituting the given values:
Change in momentum = 21.0 kg - 16.0 kg = 5.0 kg
Next, divide the change in momentum by the change in time to find the magnitude of the force:
Force = (change in momentum) / (change in time)
Substituting the given values:
Force = 5.0 kg / 0.5 sec = 10.0 N
Therefore, the magnitude of the force is 10.0 N.
