A Car's Acceleration Calculation
A car starts from rest and accelerates uniformly for a distance of 204 m over a 6.5-second time interval. The car's acceleration is _____ m/s².
Answer: 8.10m/s²
Explanation:
Using the second equation of motion: s = ut + 1/2at²
As initial velocity (u) = 0, the equation simplifies to:
s = 1/2at²
204 = 1/2 * a * (6.5)²
408 = a * (42.25)
a = 408 / 42.25
a = 9.63 m/s²
What is the acceleration of the car? The acceleration of the car is 9.63 m/s².
