Concept explainers
Projectile trajectories A projectile (such as a baseball or a cannonball) launched from the origin with an initial horizontal velocity u0 and an initial vertical velocity v0 moves in a parabolic trajectory given by
where air resistance is neglected and g ≈ 9.8 m/s2 is the acceleration due to gravity (see Section 11.7).
- a. Let u0 = 20 m/s and v0 = 25 m/s. Assuming the projectile is launched over horizontal ground, at what time does it return to Earth?
- b. Find the integral that gives the length of the trajectory from launch to landing.
- c. Evaluate the integral in part (b) by first making the change of variables u = −gt + v0. The resulting integral is evaluated either by making a second change of variables or by using a calculator. What is the length of the trajectory?
- d. How far does the projectile land from its launch site?
