Question

A bus start from rest. If the acceleration in 2m/s square, find the distannce travelled and the velocity after 2 seconds.

Answer 1

Answer:

7

Explanation:

the velocity after 2 sec is

v=u+a/t

v=0+2into 2=4

distance[s] can found through

v square=u square +2into a into s

4*2=0*2+2*2*s

16=0+4s

s=4 m

[s]=ut+ 1/2 at sq

s=0 1/2 *2*2 sq

=1*2*2

so; s=4;;;;;;;;;;;;;;
