- A projectile is fired with a speed of 15m/s at an angle of elevation of 30 degrees above the horizontal. a) At what height will it strike a vertical wall distant 18m horizontally from the gun? b) Find the magnitude and direction of its velocity when it strikes the wall.a projectile is launched at an angle theta with respect to the horizontal and air resistance is neglected. A) at what angle should you launch it so that it will achieve the maximum time in the air? B) what would be its range in that case?A projectile with an initial velocity of 59.0 m / s is launched at an angle of 35.0 ° above the horizontal. The projectile lands on a hillside 3.80 s later. Neglect air friction. (Suppose the + x axis goes to the right and the + y axis goes up along the page). (a) What is the velocity of the projectile at the highest point of its trajectory? (magnitude m / s and direction ° (counterclockwise from the + x axis) b) What is the straight-line distance from where the projectile was launched to where it hits its target?
- During a tennis match, a player serves the ball at 23.6 m/s, with the center of the ball leaving the racquet horizontally 2.60 m above the court surface. The net is 12.0 m away and 0.900 m high. When the ball reaches the net, (a) what is the distance between the center of the ball and the top of the net? (b) Suppose that, instead, the ball is served as before but now it leaves the racquet at 5.00° below the horizontal. When the ball reaches the net, what now is the distance between the center of the ball and the top of the net? Enter a positive number if the ball clears the net. If the ball does not clear the net, your answer should be a negative number. Use g=9.81 m/s?. Please explain step by step with drawing.. thank you.What is the range in meters of a projectile launched at an angle of θ1 = 78.3° with an initial speed of 58 m/s?3 parts, A projectile is shot from the edge of a cliff 115 mm above ground level with an initial speed of 65.0 m/sm/s at an angle of 35.0 ∘∘ with the horizontal, as shown in the figure (Figure 1) . d) At the instant just before the projectile hits point P, determine the magnitude of the velocity. e) At the instant just before the projectile hits point P, determine the angle made by the velocity vector with the horizontal. f) Find the maximum height above the cliff top reached by the projectile.

- 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.3. A cannon on Earth (located at the origin) launches a projectile, of mass m, horizontally at height y = 0 m with speed vo, as shown in the figure below: y (m) ↑ x (m) Fw There is a strong wind that imparts a force with constant magnitude Fw, in the negative x-direction, on the projectile as it is airborne. VoConsider a projectile being launched with an initial speed of 43 m/s at a variety of initial angles. Refer to the figure. What is the range, in meters, of the projectile if it is launched at an angle of θ1 = 79.7°? What is the range, in meters, of the projectile if it is launched at an angle of θ2 = 40.5°? What is the range, in meters, of the projectile if it is launched at an angle of θ3 = 90 − 79.7°, the complement of θ1?
