Question

A car moving at 36 km per hour accelerales uniformly to achive
a speed of 72 km per her in 30 sec. Calculate the acceleration.​

Answer 1

Answer:

convert 36 km/h and 72km/h into m/s u will get 10 m/s for 36km/h and 20m/s for 72 km/h.

initial velocity =10m/s

final velocity= 20m/s

time =10 sec

acceleration = (v-u)÷t

=(20-10)÷10

=1 m/s^2

distance= ut +1/2at^2

=10×10+1/2×1×10×10

=100+ 50

=150m
