Question

4. 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 FORCE is doubled?
a) 40 m/s/s
I
b) 20 m/s/s
c) 10 m/s/s
d) 5 m/s/s

Answer 1

F=ma
=> 20=10m so m=2
Then the force is doubled 20.2=40
F'=ma'
m does not change so 40=2.a'
a'=20 which is option b.
Give a brainliest please:-)
