Fex = 15000 N. ?
m = 500kg
a = Fex/m = 15000/500 = 30 m/s^2.
What is the acceleration at point A?
m = 500kg
a = Fex/m = 15000/500 = 30 m/s^2.
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.
