Material b has highest heat
The car gets accelerated to 10 m/s² to reach the final velocity of 65 m/s from 30 m/s in 3.5 seconds.
Answer:
Option C.
Explanation:
Acceleration is the ratio of change in velocity to the time taken to reach the final velocity. As here the initial velocity of car is given as 30 m/s and the final velocity is given as 65 m/s. So to reach this final velocity the car is taking a time of 3.5 seconds.
Thus, acceleration = change in velocity/Time
Acceleration = (65-30)/3.5 = 10 m/s²
So the car gets accelerated to 10 m/s² to reach the final velocity of 65 m/s from 30 m/s in 3.5 seconds.
