A tram car weighing 6 t travels at a speed of 18 km / h along a curvature with a radius of 100 m. Determine the force acting on the car.

Given:
m = 6 tons = 6000 kilograms – the mass of the tram car;
v = 18 km / h = 5 meters per second – the speed of the tram car;
r = 100 meters – radius of curvature of the road.
It is required to determine F (Newton) – the force acting on the tram car.
Let us find the centripetal acceleration acting on the car:
a (q) = v ^ 2 / r = 5 ^ 2/100 = 25/100 = 0.25 m / s2.
Then the force acting on the car will be equal to:
F = m * a (q) = 6000 * 0.25 = 1500 Newton = 1.5 kN.
Answer: the force acting on the tram car is 1.5 kN.
