in a performance test, each of two cars takes 9.0 s to accelerate from rest to 27 m/s. car a has a mass of 1400 kg, and car b has a mass of 1900 kg. find the net average force that acts on each car during the test.

Answer 1

Car A=5200N

Car B=5700

Step-by-step explanation:

F=ma

a= v-u

t

27-0

9

=3

F= 1400×3

=4200N

F=1900×3

=5700N
