Atoy rocket is launched vertically from ground level (y = 0 m), at time t = 0.0 s. the rocket engine provides constant upward acceleration during the burn phase. at the instant of engine burnout, the rocket has risen to 64 m and acquired a velocity of 60 m/s. the rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground. the time interval (in s), during which the rocket engine provides upward acceleration, is closest to: ? .

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
