Question

(5). A car is going backwards at 5 m/s. After 10 s of
uniform acceleration, the car is going forward at 10 m/s.
The acceleration is
A 0.5 m/s2
B. 0.75 m/s2
5 m/s
e. 1.5 m/s2 D. 5 m/s​

Answer 1

Answer:

1/2 m/s square

given: U = initial velocity = 5m/s

t = time = 10s

v = final velocity = 10m/s

solution : according to the formula, v= u + at,

we have,a = (v-u)/t

substituting the values ,we have,

a = (10-5)/10m/s square = 5/10 m/s square

= 1/2 m/s square
