A 800 kg car pushes a 1900 kg 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 4000 N . Rolling friction can be neglected.
What is the magnitude of the force of the car on the truck?
What is the magnitude of the force of the truck on the car?
Homework Answers
A.
Fct = mt*a
a = F/(m1+m2)
Fct = 1900*4000/(1900+800)
Fct = 1900*4000/2700 = 2814.81 N
B. according to newtons third law the 2 forces in this question are equal and opposite
Ftc = -2814.81 N
|Ftc| = 2814.81 N

A 1290 -kg car is pushing an out-of-gear 2140 -kg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of the car push horizontally against the ground with a force of 4600 N . The rolling friction of the car can be neglected, but the heavier truck has a rolling friction of 770 N , including the "friction" of turning the truck's drivetrain.

Q4: Yena, David and Sun find their 1 200 kg car has run out of gas after a snow storm. They all decide to push the car. Yena pushes with a force of 600 N [N 35 o E], David pushes with a force of 650 N [E 35 o N] and Sun pushes with force of 625 N [ W 40 o N]. Assuming no friction, determine the acceleration of the car.
