7. Your friend's Frisbee has become stuck 27 mabove the ground in a tree. You want to dislodge the Frisbee by throwing a rock at it. The Frisbee is stuck pretty tight, so you figure the rock needs to be traveling at least 5.1 m/s when it hits the Frisbee. If you release the rock 1.7 m above the ground, with what minimum speed must you throw it?
Your toy is stuck on the house roof and to get it down you throw a rock at it. You throw the rock from 2 meters off the ground at 40° above the horizontal. If the toy is 5 meters from the ground and you are 16 meters from the house, how fast will you need to throw the rock in order to hit the toy on the roof?
You stand at the top of an 80m-high cliff and throw a rock with speed 43 m/s at an angle 30° below the horizontal. How long will it take for the rock to hit the ground? 9.35 s 10.35
on level ground, you stand 30.0 m from the base of a tree and determine that the treetop is at 42 degrees above the horizontal, as measured from ground level. how tall is the tree?
In the middle of the night you are standing a horizontal distance of 14.0 m from the high fence that surrounds the estate of your rich uncle. The top of the fence is 5.00 m above the ground. You have taped an important message to a rock that you want to throw over the fence. The ground is level, and the width of the fence is small enough to be ignored. You throw the rock from a height of 1.60...
1. 2. Numerical Problems An aeroplane is flying horizontally at a speed of 100 m's releases a bomb at a height of 500 m. Find (1) the time taken by the to reach the ground. (ii) The horizontal distance where the bomb strikes the ground A bomb is dropped from an aeroplane when it is directly above a target at a height of 1500 m. If the speed of the aeroplane in the horizontal direction is be 540 km/h, calculate...
You stand 17.5 m from a wall holding a softball. You throw the softball at the wall at an angle of 32.5∘ from the ground with an initial speed of 30.5 m/s. At what height above its initial position does the softball hit the wall? Ignore any effects of air resistance. height:
You throw a ball towards a wall with a speed of 25 m/s and at an angle of theta o= 40 degrees above the horizontal. The wall is at a distance of 22 m from the release point of the ball. (a) How far above the release point does the ball hit the wall? (b) What are the (i) horizontal and (ii) vertical components of its velocity as it hits the wall?
Question 7 Constants Part A In the middle of the night you are standing a horizontal distance of 14.0 m from the high fence that surrounds the estate of your rich uncle. The top of the fence is 5.00 m above the ground. You have taped an important message to a rock that you want to throw over the fence. The ground is level, and the width of the fence is small enough to be ignored. You throw the rock...
You stand 17.5 m from a wall holding a baseball. You throw the baseball at the wall at an angle of 24.5 from the ground with an initial speed of 22.5 m/s. At what height above its initial position does the baseball hit the wall? Ignore any effects of air resistance.
