A skier starts from rest and slides 9.0 m down a slope in 3.0 s. Assuming constant acceleration, in
what time after starting will the skier acquire a speed of 24 ms?

Respuesta :

Answer:

3 seconds

Explanation:

  initial velocity = 0ms

  final velocity = 24ms

  time(1) = 3s

  acceleration = ?

  time (2) =?

 solution:-

                          to find acceleration,

                 a =( vf - vi ) / t

                    = 24-0 /3

                    = 24/ 3

                 a= 8ms^-2

                          To find time(2)

                 t= (vf - vi )/ a

                   = 24- 0 / 8

                   = 24/ 8

                   = 3seconds
