Question

A motorcyclist changes the velocity of his bike from 20.0 meters/second to 35.0 meters/second under a constant acceleration of 4.00 meters/second2. How long does it take the bike to reach the final velocity?

Answer 1

this is a physics question, and should have been posted there instead of in chemistry.

for constant acceleration,
\[v_f - v_i = at\]
you know \(v_f = 35.0 \text{ m/s}\), \(v_i = 20.0 \text{ m/s}\), \(a = 4.00 \text{ m/s}^2\)
Solve equation for \(t\) and plug in the numbers...

Answer 2

its chemistry

Answer 3

well on chemistry any way
