Question

a car start from rest and travels with an uniform acceleration. the car travels 100min 5s. what will be its final velocity

Answer 1

Answer:

Final velocity =40 m/s

Explanation:

GIVEN:

     Initial velocity= 0 m/s [ starts from rest ]

      time taken=5 sec

     distance travelled = 100 m

 TO FIND : final velocity

      we know ,

                 s = ut + 1/2at^2

                 100= 0(5)+1/2 x a x (5)^2

                  100= 0+25a/2

                   100=25a/2

             :. a=8 m/s^2

      now,

            v=u+at

            v= (0)+ 8(5)

           :. v= 40 m/s
