Question

please help me .I will mark as the brainlist​

Answer 1

Answer:

Explanation:

answer of part a)  acceleration = v-u / t

   14--10 /  =  0.8

b)   distance = speed*time

      18*5=90

c) yes it is an accelerated motion because aceleration is positive change in velocity and from 5 to 15 sec velocity increased

hope it is helpful to you

mark it as brainliast

Answer 2

Answer:

a. acceleration= change in velocity  / time

                         = 4m/5sec

                            = 0.8 m/sec

b. time* speed= 18*5= 90

c.Yes it is an accelerated motion because acceleration is positive change in velocity and from 5 to 15 sec velocity increased
