Amotorcycle moving at a velocity of 20 m/s accelerates uniformly at 2 the velocity of the motorcycle will be m/s after 10 seconds. question 4 options: a. none of the below b. 42 c. 40 d. 22

C. 40 m/s

To solve this, we are using the kinematic equation for final velocity:

where

is the final velocity

is the initial velocity

is the acceleration

is the time

We know from our a problem that a motorcycle moving at 20 m/s accelerates uniformly 2 m/s^2 for 10 seconds, so , , and .

Now we can replace the values

We can conclude that the velocity of the motorcycle will be 40 m/s after 10 seconds.
