Question

If the treadmill’s initial speed is 1.7 m/s, what will its final speed be?

Answer 1

b. Since Dv = vf - vi
vf = 1.7 m/s + 1.4 m/s = 3.1 m/s

Answer 2

@nitinz570 gd job,,,
but Vf² = Vi² +2as
Vf=sqrt(Vi² + 2as)
Here we know Vi = 1.7 m/s, a = 4.8 x 10^-3 m/s²

But we don't know s, the total distance traversed on the treadmill.
