Question

A car travels from rest with constant acceleration a for t seconds, If it moves along straight road the average speed is v = _________ [ ]

Answer 1

Answer:

Rectilinear motion is the answer of this

Answer 2

Answer:

v=at/2. option C) is right

Step-by-step explanation:

u=0 , a, t,

by using s=ut+1/2(at^2)

s=0×t + 1/2(at^2)

s=(at^2)/2

average speed= total distance travelled/ total time taken

v=s/t

v=(at^2)/2/t

v=(at^2)/2t

v=at/2. answer
