QUESTION 7
A car starts from the rest and attains
a speed of 8 m/s in 2 seconds. It
travels with uniform speed for next 3
s. The total displacement of the car in
5 s is
A
4 m​

Answer 1

Answer:

bro it is easy

Step-by-step explanation:

starts from rest

so

v initial or u = 0m/s

and v for 1dt case is 8m/s

so displacement is 4m

now in 2nd case states that uniform speed for 3 seconds

displacement is 8-8/3

which is zero

now total displacement is 4+0

so 4 m is answer
