A student standing on a cliff that is a vertical height d = 8.0 m above the level ground throws a stone with velocity v0 = 15 m/s at an angle θ = 29 ° below horizontal. The stone moves without air resistance; use a Cartesian coordinate system with the origin at the stone's initial position. With what speed, vf in meters per second, does the stone strike the ground? vf = If the stone had been thrown from the clifftop with the same initial speed and the same angle, but above the horizontal, would its impact velocity be different? Yes or No

Standing on top of a tower, a man launches a stone at time t=0 from a point 15.0 m above ground level. At the instant of launch, the stone has a speed of u = 5.00 m s-¹ and moves in a direction that makes an angle of 30° with the horizontal x-axis. At t = 2.00 s, the stone is still above ground level. 5x = Sy = 18 What are the x- and y-components of the stone's displacement relative to its launch point at time t = 2.00 s, and what is the stone's distance from its launch point at this time? Enter numbers, correct to 2 significant figures, in the three empty boxes below: S = 30 X B m m X В

A father demonstrates projectile motion to his children by placing a pea on his fork's handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 7.39 m/s at an angle of 73.0° above the table. With what speed (in m/s) does the pea strike the ceiling 2.10 m above the table? HINT Use the kinematic equations to find the x- and y-components of the pea's velocity when it hits the celing. Then use the Pythagorean theorem to find the speed.
