The car travels with constant acceleration reaching a speed of v m/s after 6 seconds.

the car then travels at a constant speed of v m/s for a further 2 seconds.

the car travels a total distance of 150 meters

work out the value of velocity

Explanation:

time = 2s + 6s = 8s

distance = 150m

speed = ?

velocity = ?

speed = distance ÷ time

        v = d / t

        v = 150 / 8

        v = 18,75 m/s

i'm not sure about velocity only the total speed

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

d

explanation:

v=uf/(u-f)
