3 EASY QUESTIONS! EASY 300 POINTS!

1.)Momentum is
A scalar property of mass.
A property that is subject to change based upon temperature.
A property that increases as mass increases.
ALL of the above

2.)Impulse is
The product of the average force and the time interval it is applied.

The area under the force versus time curve.

Equal to the change in momentum

All of these statements are true.

3.)A force is applied to an object giving it a net impulse. The force vs. time curve is triangular with a peak at 10N and a time interval of 10 miliseconds. What is the impulse equal to in kg m/s?

0.1 kg m/s.
100 kg m/s
0.05 kg m/s
50 kg m/s

Explanation / Answer

1) A property that increases as mass increases.

2) All of these statements are true

3) Impulse = 1/2 * 10 * (10* 10^-3) = 1/20 = 0.05 kg m/s
