Question

A bicyclist is traveling 20 m/s with an acceleration of 3 m/s2. How fast is the bicyclist traveling at the end of 10

seconds?

Answer 1

130 m/s

From the question we are finding the final
velocity of the bicycle
To find the final velocity given the initial
velocity , acceleration and time we use the
formula
V= utat
where
vis the final velocity
u is the initial velocity
a is the acceleration
t is the time
From the question
u= 10 m/s
a=6 m/s?
†= 20 s
Substitute the values into the above
formula and solve
That's
V = 10 + 6(20)
=10 + 120

We have the final answer as
130 m/s
