Find the tangential and normal components of the acceleration vector for the curve r(t) = ( 4t, 2t5, 4t) at the point t = 2 T a(2): = IZ Application: Projectile Motion A baseball is hit from a height of 3.8 feet above the ground with an initial velocity of 157 feet per second and at an angle of 47 above the horizontal. What is the maximum height reached by the baseball? Neglect air resistance. The fence at the edge of the field is 9.5 feet tall and located 380 feet from home plate. Will the ball pass over the fence? O No Yes Application: Projectile Motion A cannon is fired at an angle of 34 with the horizontal. If the cannonball has an initial velocity of 720 feet per second, how far (horizontally) will the shot travel? Assume the initial height of the projectile is 0 feet, and neglect air resistance.
