Question

a car accelerates uniformly from 18 km h -1 to 36 km h-1 in 5 s. calculate 1 the acceleration and 2 the distance covered by the car in that time .​

Answer 1

Answer:

It's Very Easy See Child

first we convert The kmh-1 to ms-1 as because the unit of Velocity is ms-1 and after we get the value we then calculate the acceleration by a=v( Final Velocity) -U(intial Velocity) / time , here final velocity is 36 kmh-1 and Initial is 18kmh-1( you convert it to ms-1) ,and time is 5s and you get the value of Acceleration

Now they are telling that what is the distance ...

See we have the speed and also the time hence following formula of distance=Speed*time we get it ......Hope it may Help
