Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?

Velocity, v = 100 m/s

Explanation:

It is given that,

Initial speed of the train, u = 0

Acceleration of the train,

Let v is the velocity of the train at the end of 20 seconds, t = 20 s

Using the equation of kinematics as :

v = u + a × t

v = a × t

v = 5 × 20

v = 100 m/s

So, the velocity of the train after 20 s is 100 meters. Hence, this is the required solution.

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
