Question

an object at rest start moving with uniform motion of 1 metre per second square calculate the distance travelled by it in 4 seconds​

Answer 1

Answer:

80 meter is the answer.......

Answer 2

u = 0(since started from rest)

v = 1m/s

t = 4seconds

Acceleration = v-u/t

                       = 0- -1/4

                        = 1/4 = 0.25m/s²

Now we can substitute the values

 s = ut + 1/2at²

     = 0 × 4 + 1/2 × 0.25 × 4²

    = 0 + 1/2 × 0.25 × 16

    = 0 + 1 × 0.25 × 8

     =0.25 × 8

      = 2 m

Distance travelled = 2m
