Question

3. A 20 N force pushes a cart. That cart accelerates at a rate of 10 m/s/s. What will the acceleration of the

cart be if the MASS is doubled?

Answer 1

5m/s

Step-by-step explanation:

M = f/a
M = 20/10

M = 2Kg

If mass is is doubled, (4kg), the acceleration will be one half of its original value if the force applied is the same (20N) .

a = f/m
a = 20/4

a = 5m/s
