A projectile is launched from the top of the cliff of height h with initial velocity v0 and launch angle ? with respect to the horizontal. It later hits the ground. Derive an expression for the magnitude and direction angle of the velocity as the object hits the ground in terms of some or all of the variables given in the problem h, v0 , ?, and g.
An object is launched at a velocity of 20 m/s in a direction making an angle of 45° upward with the horizontal.
a) What is the maximum height reached by the object?
b) If the object has a time of flight of 2.9 s, what is the horizontal range of the object?
Problem 4: An arrow is shot from a height of 1.95 m toward a cliff of height H. It is shot with a velocity of 28 m/s at an angle of 60° above the horizontal. It lands on the top edge of the cliff 3.99 s later.
a) What is the height H of the cliff in meters
b) what is the maximum heigh reached by the arrow along its tragectory in meters
