Some bags (the mass of each bag is 50 kg) are put in the truck of 200 kg mass. After applying 400 N force the car started moving with 1 m/s accelaration.Now my question is'', how many Bags are in the truck?

Answer 1

This we need to make two assumptions:
1. The car is on a perfectly horizontal plane/road
2. The car is in neutral AND friction is negligible.

Use Newton's second law: F=ma
F=400N
m=(200 + 50n ) kg
n=number of bags.
a=1 m/s^2 (acceleration is measured in m/s^2)

Set up equation and solve for n:

400=(200+50n)*1
