Question

A body starts from rest and first accelerates with magnitude A for time t and then with acceleration 2A for time

2t. Find the velocity at the end of time 3t and distance traveled in this time. What is the average velocity for the

whole motion.
​

Answer 1

Answer:

2Useful equations related to acceleration, average velocity, final velocity and distance traveled

Average Velocity. va = (v1 + v0) / 2 (1) ...

Final Velocity. v1 = v0 + a t (2) ...

Distance Traveled. s = (v0 + v1) t / 2 (3) ...

Acceleration. a = (v1 - v0) / t (4) ...
