Q2 The Velocity of a
a care increases from
15 km/hr 33 km/hr in 20s
Find is acceleration.

Answer 1

Answer:

initial velocity/u=15km/h=(15×5÷18)m/s=45/18m/s

final velocity/v=33km/h=(33×5÷18)m/s=165/18m/s

time/t=20s

acceleration=final velocity-initial velocity÷time

=165-45÷18×1÷20(reciprocal of 20)

=120÷18x20

=6÷18(dividing 120 and 20)

=0.3333......

acceleration=0.33...m/s^2
