A man stands on the roof of a 15.0-m-tall building and throws a rock with a speed of 30.0 m/s at an angle of 33.0° above the horizontal. Ignore air resistance. Calculate (a) the maximum height above the roof that the rock reaches; (b) the speed of the rock just before it strikes the ground; and (c) the horizontal range from the base of the building to the point where the rock strikes the ground, (d) Draw x-t, y-t, υx-t, and υy-t graphs for the motion.

- A boy stands on the roof of a 20-m tall building and throws a ball with a speed of 35 m/s at an angle of 40° above the horizontal. Ignore air resistance. Calculate (a) the maximum height above the roof that the ball reaches; (b) the time to reach maximum height; (c) the total time of flight; (d) the velocity of the ball just before it strikes the ground; and (e) the horizontal range from the base of the building to the point where the ball strikes the ground.arrow_forwardAn attacker at the base of a castle wall 3.80 m high throws a rock straight up with speed 8.40 m/s from a height of 1.40 m above the ground. (a) Will the rock reach the top of the wall? Yes, No (b) If so, what is its speed at the top? If not, what initial speed must it have to reach the top? m/s(c) Find the change in speed of a rock thrown straight down from the top of the wall at an initial speed of 8.40 m/s and moving between the same two points. m/s(d) Does the change in speed of the downward-moving rock agree with the magnitude of the speed change of the rock moving upward between the same elevations? Yes, No (e) Explain physically why it does or does not agree.arrow_forward"A person stands on the ground 60m away from a cliff with a height h. They throw a ball toward the cliff with a speed of vp = 30 m/s and an angle of 60° above the horizontal. It lands on top edge of the cliff some time later. How high is the cliff, and what is the ball's impact speed?"arrow_forward
- An attacker at the base of a castle wall 3.60 m high throws a rock straight up with speed 8.20 m/s at a height of 1.50 m above the ground. (a) If so, what is the rock's speed at the top? If not, what initial speed must the rock have to reach the top? m/s(b) Find the change in the speed of a rock thrown straight down from the top of the wall at an initial speed of 8.20 m/s and moving between the same two points. m/s(c) Does the change in speed of the downward-moving rock agree with the magnitude of the speed change of the rock moving upwards between the same elevations? Explain physically why or why not.arrow_forwardA golf ball rolls off a horizontal cliff with an initial speed of 11.1 m/s. The ball falls a vertical distance of 17.2 m into a lake below. (a)How much time does the ball spend in the air? (b) What is the speed v of the ball just before it strikes the water?arrow_forwardA rock is thrown off a cliff at an angle of 53° with respect to the horizontal. The cliff is 100 m high. The initial speed of the rock is 30 m/s. (a) How high above the edge of the cliff does the rock rise? (b) How far has it moved horizontally when it is at maximum altitude? (c) How long after the release does it hit the ground? (d) What is the range of the rock?

(b) If so, what is its speed at the top? If not, what initial speed must it have to reach the top? (c) Find the change in speed of a rock thrown straight down from the top of the wall at an initial speed of 4.50 m/s and moving between the same two points. (d) Does the change in speed of the downward-moving rock agree with the magnitude of the speed change of the rock moving upward between the same elevations? (e) Explain physically why it does or does not agree.arrow_forwardA man stands on a roof of a 15.0-m tall building and throws a rock with a velocity of magnitude 30m/s at an angle of 33.0° above the horizontal.you can ignore air resistance. Calculate the maximum height above the roof reached by the rock.arrow_forwardTwo friends are playing catch. They both are about the same height so the release height of the ball when thrown and the height of the catch are both 1.75 meters above the ground. The friend on the right throws the ball at a speed of 15 m/s at an angle of 33° above the horizontal. Assume you can ignore air resistance for this problem. (1) What are the horizontal and vertical components of the initial velocity of the ball? (2) How far away should the second friend stand to catch the ball (at a height of 1.75 m above the ground)? 1: You'll first need to solve for the time the ball is in the air. 2: If you don't know how to solve for time, then pick a value for the time the ball is in the air and perform your remaining calculations using that value for timearrow_forward
- The archerfish uses a remarkable method for catching insects sitting on branches or leaves above the waterline. The fish rises to the surface and then shoots out a stream of water precisely aimed to knock the insect off its perch into the water, where the archerfish gobbles it up. Scientists have measured the speed of the water stream exiting the fish’s mouth to be 3.7 m/s. An archerfish spots an insect sitting 19 cm above the waterline and a horizontal distance of 30 cm away. The fish aims its stream at an angle of 39° from the waterline. Does the stream hit its mark?arrow_forwardUse the technique of separating the problem into X- and Y- components to solve this problem: A Halloween prankster throws an egg out the window of an office building down onto the parking lot below. The egg is thrown with a velocity of 18 meters / second, at an upward angle of 23 degrees, and is release exactly 53 meters above the surface of the parking lot. The egg lands on the roof of a parked SUV, 2 meters above the surface of the parking lot. Using a gravitational constant, g, of 9.8 meters / second² calculate the following: 1) The time it takes for the egg to hit the parked SUV. (seconds) 2) The total distance away from the building that the egg lands. (meters)arrow_forwardA ball rolls horizontally off the edge of a tabletop that is 1.40 m high. It strikes the floor at a point 1.51 m horizontally away from the table edge. (Neglect air resistance.) (a) How long was the ball in the air? (b) What was its speed at the instant it left the table?arrow_forward
