Question

a car moving in a straight line from rest at equal to zero it accelerates with 2 meter per second square.Solve the following table
Time-2sec,?,?,10min
Displacement-?,?,25m,?
Speed-?,10m/s,?,?​

Answer 1

Explanation:

Given, Speed=18km/h,t=5s

a)The speed of the car in m/s=18×

18

5

=5 m/s

b) The retardation is:

a=

t

v−u

=

5

0−5

=1m/s

2

c) The velocity of the as a funcition of time 2sis:

v(t)=5−t⇒v(t)=5−2=3m/s=10.8 km/h
