Question

Q 4,5,6 plz I am not able to solve..........

Answer 1

Answer:

ok... Here we go Q.no.4 -->

U- INTIAL VELOCITY

V-FINAL VELOCITY

A- ACCELERATION

Explanation:

U= 18.5 m/s

V = 46.1 m/s

t= 2.47 s

a=?

as we know....

V= U+AT

46.1 = 18.5 + a*2.47

27.6/2.47 = a

which gives

a= 11.17 m/s^2

Hope that helps!!

Answer 2

Answer:

this is answer of ques. 4

initial velocity=18.5m/s=u

final velocity=46.1 m/s=v

time =2.47s=t

as we know

a= v-u/t

a =46.1-18.5/2.47

a=27.6/2.74

a=11.17 m/s^2

now

we know that

s= ut+1/2at^2

s=18.5x2.47+1/2 11.17 x2.47

s=45.695 + 13.79495

s=59.48995m
