A rocket is fired vertically and reaches a speed of 34.3 m/s in half a second. One and a half seconds later the rocket’s speed is 19.6 m/s. Find the acceleration (in m/s2) and initial velocity (in m/s) of the rocket. Complete the equation of motion for the velocity of the rocket:

Question

A rocket is fired vertically and reaches a speed of 34.3 m/s in half a second.  One and a half seconds later the rocket’s speed is 19.6 m/s.  Find the acceleration (in m/s2) and initial velocity (in m/s) of the rocket.  Complete the equation of motion for the velocity of the rocket:

v(t) =   t +

Assume a standard coordinate system where the upward vertical direction is positive and downward vertical direction is negative.
