Question

2. A net force of 30 N causes a mass to accelerate at a rate of 6 m/s2. Determine the mass.
3. How much force is needed to accelerate a 20 kg skier in 2 m/s2?
4.What is the force on a 5000 kg elevator that is falling freely at 9.8 m/s2?

Answer 1

Explanation:

2. f=ma. a=6. m=30

a=30/6

a=5kg.

3. f= ma. . 20*2. 40N
