Question

Sort the following forces as relevant or not relevant to this situation. The symbols are defined as follows: normal force = ñ, tension force =T, horizontal force of the road on the car = Frc, horizontal force of the road on the truck = Frt, weight = ū, force of the car pushing on the truck = Fct, and force of the truck pushing on the car = Ftc. Drag the appropriate objects to their respective bins. Reset Help Relevant Not relevant TS TH Ict Ftc

A 1200-kg car pushes a 2100-kg truck that has a dead battery to the right. When the driver steps on the accelerator, the drive wheels of the car push against the ground with a force of 4500 N . What is the magnitude of the force the car applies to the truck?

Answer 1

Ground exerts 4500 N on Car which causes acceleration of car+truck

a = 4500/(1200+2100)= 45/33

Force exerted by car on truck

= Mass of truck × acceleration

= 2100 ×(45/33)

= 2863.6 N
