Question

a car accelerates from 8 metre per second to 16 metre per second in 10 seconds find its acceleration and displacement in this time

Answer 1

Answer:

Acceleration is 0.8 meters per second squared. Displacement is 120 meters.

Explanation:

By using the formula for acceleration = (v - u)/t = (16 - 8)/10 = 8/10

= 0.8 m/s^2

Now we use the formula for displacement ( S ) = u*t + (a*t^2)/2

                                                                                 = 8*10 + (0.8*10^2)/2

                                                                                 = 80 + 40 = 120 meters
