A block of 100 kg mass is sitting on a railroad car with a mass of 2,000 kg. The railroad car is sitting on a track.
What is the free body diagram for each of the two objects?
Here variable of diiferent forces exert on free body diagram is;
w1=weight of rail road car
w2=weight of block
N1=normal force of rail road car
N2=normal force of block
F1=forward force of railroad car
F2= forward force of block
f1=N1=frictional
force of railroad car
f2=N2=frictional
force of block
COM=centre of mass
For simplicity we redraw free body diagram taking railroad car as a bigger block
Therfore for each objects four forces are applied from all four direction to cancel each other and verify the rest state i.e W1<--------------->N1
F1<--------------->N1
=f1
W2<------------------->N1 of upper surface of railroad car
N2<---------------------W2
F2<---------------------->N2
=f2

A railroad car with a mass of 13000 kg collides and couple with a second car of mass 20,000kg that is initially at rest. the first car is moving with a speed of 3.5 m/s prior to the collision. a) what is the initial momentum of the first car ? b) if external forces can be ignored, what is the final velocity of the two railroad cars after they couple.
A railroad freight car, mass 15 000 kg, is allowed to coast along a level track at a speed of 3.0 m/s. It collides and couples with a 54 000-kg loaded second car, initially at rest and with brakes released. What percentage of the initial kinetic energy of the 15 000-kg car is preserved in the two-coupled cars after collision? Answer options below. A. 14% B. 18% C. 78% D. 22% E. 38%
A railroad car of mass 3.25e4 kg is moving at 3.25 m/s collides and couples with two couples railroad cars, each of the same mass as the single car and moving in the same direction at 1.20m/s. A) what is the speed of the three coupled cars after the collision? B) how much kinetic energy is lost in the collision?
An empty railroad car of mass 4400 kg is being pulled beneath a grain elevator that dumps grain at the rate of 175 kg/s. If the coefficient of friction between the car wheels and the track is 0.021, what is the force needed to keep the car moving at a constant speed of 1.9 m/s 25.0 s after the grain is first dumped on the car Points given for correct answer and explanation
A railroad car with a mass of 1.95 ✕ 104 kg moving at 2.88 m/s joins with two railroad cars already joined together, each with the same mass as the single car and initially moving in the same direction at 1.56 m/s.

An 18000 kg freight car rests against a spring bumper at the end of a railroad track. The spring has constant k=3.2×10^5 N/m. The car is hit by a second car of 9400 kg mass moving at 8.0 m/s , and the two couple together. Find the maximum compression of the spring. Find the speed of the two cars when they rebound together from the spring.
