Range of a projectile It is known from physics that the range R of a projectile is directly proportional to the square of its velocity v. (a) Express R as a function of v by means of a formula that involves a constant of proportionality k. (b) A motorcycle daredevil has made a jump of 150 feet. If the speed coming off the ramp was 70 mi/hr, find the value of k in part (a). (c) If the daredevil can reach a speed of 80 mi/hr coming off the ramp and maintain proper balance, estimate the possible length of the jump.
