An 877 kg drag race car accelerates from rest to 116 km/h in 0.951 s. What change

The change in momentum is 28265.71  kg-m/s.

Explanation:

Given that,

Mass of a car, m = 877 kg

Initial velocity of the car, u = 0 (at rest)

Final velocity of the car, v = 116 km/h = 32.23 m/s

Time, t = 0.951 s

We need to find the change in momentum produced by the force. It can be calculated as the difference of final momentum and the initial momentum.

So, the change in momentum is 28265.71  kg-m/s.

C.Warm air is usually more humid than cold air.

as the temperature increase, vapor pressure increase. this in turn decreases the humidity, hence the air can hold more water at high temperature.
