Question

an object is moving along with positive x-axis with uniform acceleration of 4 metre per second square at time t is equal to zero x is equal to 4 and equal to 2 metre per second what will be the velocity and position of the object at time t is equal to 30 second​

Answer 1

Explanation:

(I) At t=0s,

v=u+at

v=3+(4×2)

v=11m/s

And, s=5+ut+(1/2)at^2

s=5÷(3×2)+8

s=19m

(II) v=u+at

v=5+(4×2)

v=13m/s

And, s=ut+(1/2)at^2

s=5+(5×2)+8

s=23m                                                   BRAINLY
