A missile is launched from the ground with a speed of 100 m/s at an initial angle of 45 degrees to the ground. In what direction is it moving just 2 seconds before hitting the ground (to the nearest degree)?

A batter hits a baseball 3 ft above the ground, so that the ball leaves the bat with a speed of 120 ft/s and at an angle 60° above horizontal. (a) How far will the baseball travel until it first hits the ground? (b) What will be the maximum height of the baseball? (c) What is the speed that the baseball is traveling at when it first hits the ground?

In the figure, you throw a ball toward a wall at speed 28.0 m/s and at angle θ0 = 42.0˚ above the horizontal. The wall is distance d = 20.0 m from the release point of the ball. (a) How far above the release point does the ball hit the wall? What are the (b) horizontal and (c) vertical components of its velocity as it hits the wall?

A guy is standing on a relatively flat surface (h = 0 m). A pesky drone is flying overhead at a height of 120 m above the ground and with a velocity of 15 m/s. The guy gets annoyed and fires an arrow with an initial velocity of 100 m/s the instant the horizontal distance between him and the drone is 5 m. At what angle must he fire the arrow in order to hit the drone? Take the guy's height to be 1.8 m. Just to clarify, would shooting an arrow follow the same rules as a regular projectile motion problem? Thanks.

A projectile is launched with a speed of 140 m/s at an angle of 45 degrees above the horizontal, from a height of 1500 m above the ground. How far does it travel in the horizontal direction before hitting the ground?

A skateboarder shoots off a ramp with a velocity of 7.9 m/s, directed at an angle of 51° above the horizontal. The end of the ramp is 1.4 m above the ground. Let the x axis be parallel to the ground, the +y direction be vertically upward, and take as the origin the point on the ground directly below the top of the ramp. (a) How high above the ground is the highest point that the skateboarder reaches? (b) When the skateboarder reaches the highest point, how far is this point horizontally from the end of the ramp? (a) Number_____  Units_____                                                            (b) Number ____  Units ____

A rocket is launched at ground level with an initial speed of 189 ft/s, at an angle of 34° above the horizontal. It strikes a mark above the ground 2.4 seconds later.What is the vertical distance, in feet, from where the rocket was launched to where it lands?

A cart is moving with a constant horizontal velocity of 5.00 m/s. A small pebble is launched from the front of the cart with a velocity of 8.00 m/s at 60.0° above the horizontal as measured relative to the cart (see figure) and experiences no significant air resistance. Cart 60° 8.00 m/s -5.00 m/s Just as the pebble returns to the level from which it was launched, what is its distance from the front of the cart? How far did the pebble travel from its launch point relative to the ground.

An object is launched with an initial velocity of 24.5 m/s at an angle of 37.2 degrees relative to the +x direction. If it is initially at ground level, at what distance away does it return to the ground?

Spitting cobras can defend themselves by squeezing muscles around their venom glands to squirt venom at an attacker. Suppose a spitting cobra rears up to a height of 0.520 m above the ground and launches venom at 2.50 m/s, directed 37.0° above the horizon. Neglecting air resistance, find the horizontal distance (in m) traveled by the venom before it hits the ground.
