A projectile is fired from the point (0, 0) with an initial velocity of 0 m/s
Question:
A projectile is fired from the point (0, 0) with an initial velocity of ν0 m/s at an angle α above the horizontal. If we assume that air resistance is negligible, then the position (in meters) of the projectile after t seconds is given by the parametric equations
where g = 9.8 m/s2 is the acceleration due to gravity.
(a) Find the speed of the projectile when it hits the ground.
(b) Find the speed of the projectile at its highest point.
