a bobsled has a momentum of 1500 kg*m/s to the south. Air resistance reduces its momentum to 750 kg*m/s to the south. What impulse is applied to the bobsled by the air resistance?

Respuesta :

AL2006
The impulse is exactly the change in momentum,
and they have the same units.

The impulse imparted to the bobsled by the air
resistance is

                       (750 - 1500) = -750 kg-m/s.

It's negative because it reduced the bobsled's momentum.

If the impulse had come from a rocket engine on the back of
the bobsled, then it would have been a positive impulse.

When a bobsled has a momentum of 1500 kg*m/s to the south. Air resistance reduces its momentum to 750 kg*m/s to the south then the impulse is applied to the bobsled by the air resistance is  750 kg*m/s to the east.

What is impulse?

The product of the average applied force and the time for which it is exerted is known as an impulse. The unit for the impulse of force is the same as that of momentum which is kg*m/s

The mathematical relation for impulse is

Impulse  = F * Δt =change in momentum

where F represents the force applied and Δt represents the time for which the force is applied

As we know from the above relation the change in momentum of an object is equal to the impulse of the force

Impulse applied by the air resistance = (1500 - 750) kg*m/s toward the east

Thus, the Impulse applied by the air resistance comes out to be 750 kg*m/s to the east.
