Question

An aeroplaerates uniformly such that
it goes from rest to 144m/s in 8 sec

Calcute the acceleration required
and the total distance it has travelled
in this timente inrt​

Answer 1

Answer:

Initial velocity of car is u=0m/s. Velocity after 20 s is v=144km/hr=(144)(5/18)m/s=40m/s. ... We have to calculate the distance travelled by the car in 20 sec. ... Here the units of time and velocity ate in different system so we have to convert them. ... If the speed of the car is reduced by 8 km per hour then the same distance is ...
