A bus start from rest and then moves with a constant acceleration of 2m/s square. calculate its time of traven if its final velocity is 20 m/s​

Its Answer is 10 s.

Explanation:

As acceleration is defined as time rate of change of velocity. So,

a =   ÷ t

2 = (20 - 0 ) ÷ t

2 =  20 ÷  t

t = 20 ÷ 2

t  = 10 s

We have put initial velocity as zero because  body is starting from rest.

it becomes positively charged by charging it

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
