. A truck of mass M is moved under a force F
If the truck is then loaded with an object equal to the mass of the truck and the driving force is halved, then how does the acceleration change?
Answer: Force = mass x acceleration
When mass is doubled force is halved m becomes 2m and f becomes f/2
a2=f/4m or a2/a1 = f/4m + f/4m = 1/4
acceleration reduces to 1/4
