Projectile problems
More practice problems. Yes… more. This time on projectile motion.2. Billy-Joe stands on the Talahatchee bridge kicking stones into the water below.
a) If Billy-Joe kicks a stone with a horizontal velocity of 3.50 m/s, and it lands in the water a horizontal distance of 5.40 m from where Billy-Joe is standing, what is the height of the bridge?
b) If the stone had been kicked harder, how would this affect the time it would take to fall?
4. Ferdinand the frog is hopping from lily pad to lily pad in search of a good fly for lunch. If the lily pads are spaced 2.4 m apart, and Ferdinand jumps with a speed of 5.0 m/s, taking 0.60 s to go from lily pad to lily pad, at what angle must Ferdinand make each of his jumps?
6. At a meeting of physics teachers in Montana, the teachers were asked to calculate where a flour sack would land if dropped from a moving airplane. The plane would be moving horizontally at a constant speed of 60.0 m/s at an altitude of 300. m.
a) If one of the physics teachers neglected air resistance while making his calculation, how far horizontally from the dropping point would he predict the landing?
b) Draw a sketch that shows the path the flour sack would take as it falls to the ground (from the perspective of an observer on the ground and off to the side.)
