A cannon ball was fired at 20m/s. If it was launched at 30 degrees above the horizontal, find (a) the components of the velocity, (b) maximum height, (c) total time of flight,

A placekicker is about to kick a field goal. The ball is 21.7 m from the goalpost. The ball is kicked with an initial velocity of 19.1 m/s at an angle above the ground. Between what two angles, 0₁ and 02, will the ball clear the 2.67-m-high crossbar? Give your answers as (a) the smaller angle and (b) the larger angle. (Hint: The following trigonometric identities may be useful: sec 0 = 1/(cos) and sec²0 = 1 + tan²0.) (a) Number (b) Number Units Units 0₂

A projectile is shot in the air from ground level with an initial velocity of 490 m/sec at an angle of 60° with the horizontal. (a)At what time (in seconds) is the maximum range of the projectile attained? (b)What is the maximum range (in meters)?

A ball is projected with an initial upward velocity component of 35 m/s and a horizontal component of 30 m/s. The maximum height reached by the ball is:
