Question

s=12(u+v)t Where s is the distance traveled by an object (in meters) with an initial velocity u (in m/s) and final velocity v (in m/s), t seconds later. Find s when u is 8 m/s, v is 12 m/s, and t is 5 seconds. A. 100 m

Answer 1

solution

Explanation:

given

u= 8mls

v=12mls

t=5sec

now,

acceleration (a)=v-u/t

12-8/5

4/5

0.8mls^2

again,

s=ut+1/2at^2

s=8×5+1/2×0.8×25

s= 40+10

s=50m
