Concept explainers
In Example 3.10, suppose the tranquilizer dart has a relatively low muzzle velocity so that the dart reaches a maximum height at a point P before striking the monkey, as shown in the figure. When the dart is at point P, will the monkey be (i) at point A (higher than P), (ii) at point B (at the same height as P), or (iii) at point C (lower than P)? Ignore air resistance.

- You are designing an artillery system with the aim of hitting a target 20 km away with two shells at the same time. The first shot will be fired at a 50-degree angle. What is the required initial velocity needed to hit the target? Assume air resistance is negligible.arrow_forwardAnswer detailly 6arrow_forwardA mortar gun, with a maximum range of 20 m on level ground, is placed on the edge of a vertical cliff of height 10 m overlooking a horizontal plane, as illustrated in the following figure. 20 m (a) Consider the sub-problem of the mortar gun on level ground with maximum range of 20 m. Show that the flight time for the projectile on level ground is V2 vo Hint: The angle required to obtain maximum range is 0 = T/4.arrow_forward
- A bullet is fired with an initial velocity v., then it passes two points both a distance h above the horizontal. Show that if the gun is adjsted for maximum range, the height h of the line AB of length L will be y Vo B 1 h = 4vo9arrow_forwardImagine an archer preparing to fire an arrow. The archer aims the arrow directly ahead, that is to say, parallel with the ground. Bows are drawn to the corner of the mouth when fired. Let's say, for this particular archer, that puts the arrow 1.8 m (about 5.5 feet) above the ground. Assume that we have measured the initial speed of arrows fired by this archer with this bow and it is 100 m/s. (Ignore wind resistance) a) At what point during the arrow's flight will it be moving the fastest? (Be careful here, think about it. You don't need to do any calculations to figure this out.) b) How long will it take for the arrow to hit the ground?c) How far will the arrow travel during this time period?arrow_forwardA frat boy throws a ping pong ball from 0.6 m above a table at 5 m/s and wants to land it in a 20 cm cup 1 m away along the table. At what angle above the horizontal should he throw it?arrow_forward
- A large cannon is fired from ground level over level ground at an angle of 300 above the horizontal. The muzzle speed is 980 m/s. Neglecting air resistance, answer the following questions: a) what is the maximum height that the projectile will reach? b) how long till the projectile will hit the ground? c) the projectile will travel what horizontal distance before striking the ground?arrow_forwardA physics student, standing 7 m from a tree, throws a roll of toilet paper up into the limbs of the tree at an angle of 65° above the horizontal. If the student throws the roll with a velocity of 12 m/s, at what height will the roll hit the tree?arrow_forwardA circus man is shot out of a cannon 500 meters above ground at a speed of 25 m/s at a launch angle of 50° what is the velocity after 5 seconds?arrow_forward
- You fire a ball with an initial speed v at an angle o above the surface of an incline, which is itself inclined at an angle 0 above the horizontal (a) Find the distance, measured along the incline, from the launch point to the point when the ball strikes the incline. (b) What angle ø gives the maximum range, measured along the incline? Ignore air resis- tance.arrow_forwardAn item with beginning speed v0 is projected from the edge of the roof of a structure of height H. The object's initial velocity produces an angle a0 with the horizontal. Don't think about air resistance. What is the speed of the item shortly before it hits the ground if a0 = -90 and the object is thrown straight down?arrow_forwardA boy wishes to throw a ball over a flat roofed school house that stands 12 m wide and 7.5 m high on level ground. Assuming that the ball will leave his hand at a height of 5 m above the ground,determine how far from the wall he should take his hand in order to make the ball clear the roof with least effort, that is, with minimum velocity.arrow_forward
