Question

An object moving with an initial velocity of 10 m/s is subjected to a uniform acceleration of -8m/s². Find the displacement in the next 2 seconds.


(pls answer )​

Answer 1

Answer:

Explanation:

initial velocity,u = 5m/s

acceleration,a = 2.5m/s²

t=4s

Apply the 2nd equation of motion,

s = ut+at²/2

s =5×4 + 2.5×4²/2

s = 20 + 20 = 40m Hence the body displacement 40 m in the next 4 seconds.
