Question

An object with an initail velocity of 4 m/s moves along a straight axis under constant accelaration. Three second later its velocity is 14 m/s. How far did it travel during this time

Answer 1

Answer:

27m

Explanation:

v=14, u=4, t=3, s=?

a=(14-4)/3

=10/3

(v)^2=2as+(u)^2

196=2×10/3s+16

196-16=20/3s

180=20/3s

s=180×3/20

s=27m
