A800kg car pushes a 1900kg truck that has a dead battery. when the driver steps on the accelerator, the drive wheels of the car push against the ground with a force of 4900n . rolling friction can be neglected.
a) what is the magnitude of the force of the car on the truck?
b) what is the magnitude of the force of the truck on the car?

Answer

given,

mass of car = 800 kg

mass of truck = 1900 kg

force acting = 4900 N

a) F = (m₁+ m₂ ) a

a = 1.815 m/s²

a) force exerted by  the car on the truck

 F = 3448.5 N

b) According to newtons third law

Force exerted by the truck on the car will be same.

Force of the truck on the car =  F = 3448.5 N

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
