A roller-coaster car has a mass of 500 k when fully loaded with passengers. If at point a the forces exerted by the truck on the car is 15000
What is the acceleration at point A?
Fex = 15000 N. ?
m = 500kg
a = Fex/m = 15000/500 = 30 m/s^2.
To find the acceleration at point A, we need to use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.
Given:
Mass of the roller-coaster car, m = 500 kg
Force exerted by the truck on the car at point A, F = 15000 N
We can rearrange the formula to solve for acceleration (a):
F = m * a
Substituting the given values:
15000 N = 500 kg * a
Now, let's solve for the acceleration (a):
a = 15000 N / 500 kg
= 30 m/s²
Therefore, the acceleration at point A is 30 m/s².
