The magnitude in ft/s of the deceleration due to air resistance of the nose cone of a small 2 experimental rocket is known to be 0.00015v, where v is expressed in ft/s. The nose cone is projected vertically from the ground with an initial velocity of 420 ft/s. Derive expressions for the speed of the cone as a function of height as the cone moves up to its maximum height and as it returns to the ground. Plot the speed of the cone as a function of the height for the upward motion and for the downward motion. 2 [Hint: The deceleration of the cone as it moves up is g + 0.00015v, and the acceleration of 2 2 the cone as it moves down is g-0.00015v, where g = 32.2 ft/s .] The magnitude in ft/s of the deceleration due to air resistance of the nose cone of a small 2 experimental rocket is known to be 0.00015v, where v is expressed in ft/s.
