Answer:
13.2m/s²
1.89s
Explanation:
Given parameters:
Initial velocity = 0m/s
Final velocity 1 = 45m/s
Final velocity 2 = 70m/s
Unknown:
Time taken = 3.4s
Solution:
Acceleration is the rate of change of velocity with time.
Acceleration = [tex]\frac{Final velocity 1 - initial velocity }{3.4}[/tex]
Acceleration = [tex]\frac{45 - 0}{3.4}[/tex] = 13.2m/s²
B. How much longer would it take the car to get up to 70m/s
Maintaining the is acceleration;
13.2 = [tex]\frac{70 - 45}{t}[/tex]
25 = 13.2t
t = 1.89s
