Question

A runner is initially going 5 m/s to the right when she slows down at to 2 m/s over 10

seconds.
a) What is her acceleration?
b) How far does she travel in these 10 seconds?

Answer 1

acceleration =-0.3

distance =0.16m

Step-by-step explanation:

the runner was initially moving with a velocity of 5mls and attained a final velocity of 2mls because it decelerated. therefore to find its acceleration you can go by the formula a=v-u÷t

the distance can be found by the formula v²=u²+2as
