Sagot :
Answer:
100Ns
Explanation:
find velocity and then plug into momentum formula momentum=(velocity)(mass)
Answer:
5,000 kg-m/s going south
Explanation:
Since you're only given mass and height, not velocity. You have to find velocity first. The equation for velocity is v=2gh. We know gravity is 10 since it's given & height is also given which is 125m. After doing the math, it's 2,500. Now that you have velocity, you can plug velocity into the formula for momentum which is p=mv. 2.0 times 2,500 = 5,000 kg-m/s going south.
