Question
The velocity of a particle is given by v=25t2 -80t-200, where velocity is meter per second and time is seconds. Determine the velocity for the first six seconds when acceleration is zero.
Answer:
v = 220 m / s
Explanation:
This is a kinematics exercise, the expression for velocity is
v = 25 t² – 80 t – 200
asks the velocity for time t = 6 s.
let’s calculate
v = 25 6² – 80 6 – 200
v = 220 m / s
