Projectile Motion AP Physics C
Range-the horizontal distance that a projectile travels
Answer the following: 1) 2) 3) 4) Which launch angle produces the greatest range? Which launch angle obtains the greatest maximum height? Which launch angle has the greatest flight time? Which launch angle has the same range as 80 degrees?
Derive the Following: Derive an expression for maximum height reach by a projectile in terms of angle and initial velocity. Derive an expression for the range of a projectile in terms of angle and initial velocity.
Javelin Thrower Example An athlete throws a javelin a distance of 80 m at the equator where g = 9. 78 m/s 2. Four years later the Olympics are held at the North Pole where g= 9. 83 m/s 2. Assuming that the thrower throws the javelin with the same initial velocity as before, how far will the javelin travel at the North Pole?
George Washington Example It has been said that in his youth that George Washington threw a silver dollar across a river. Assuming that the river was 75 m wide, a) What minimum initial speed was necessary to throw the coin across the river, and b) How long was the coin in flight?
Potato Gun Problem A spud is launched from a potato cannon with velocity 55. 0 m/s, 40. 0° and flies out into the woods. The sound of the spud hitting a tree is heard 2. 00 seconds after launch. (a) Where was the spud when it hit (i. e. what position)? (b) What was the impact speed?
