When a car traveling at 30 m/s hits the gas pedal, it speeds up to 65 m/s in 3.5 seconds. What is the car's
acceleration during that time?
A. 5 m/s
C. 10 m/s
B. 15 m/s
D. 20 m/s

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.

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.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
