Answer:
The acceleration of the car is \(2.5\frac{m}{s^{2} }\)
Explanation:
Kinematics of the problem:
The car moves with uniform accelerated movement, then, We use the acceleration equation for this type of movement:
\(a=\frac{1}{2*d} (v_{f} ^{2} -v_{i} ^{2} )\) Formula 1
vf: final speed=\(50\frac{m}{s}\)
vi: initial speed=0
d=distance traveled by the car=500m
Acceleration calculating:
We replace known information in the equation 1:
\(a=\frac{50^{2} -0}{2*500}\)
\(a=\frac{2500}{1000}\)
\(a=2.5\frac{m}{s^{2} }\)
Answer:
The acceleration of the car is \(2.5\frac{m}{s^{2} }\)
