PLEASE EXPLAIN STEP BY STEP THANK YOU SO MUCH! A child standing on the edge of a sheer cliff wall throws a rock down towards the ground below. The rock is thrown 41° below the horizontal at a speed of 22 m/s & lands 42 m from the base of the cliff wall. Ignore air drag A.) Determine how long the rock was in the air B.) Determine how high the cliff wall is. C.) Determine how fast the rock...
PLEASE EXPLAIN BOTH QUESTION STEP BY STEP. THANK YOU SO MUCH. Time in air Five balls are all at the same height near the surface of Earth. One is dropped from rest but the others are launched horizontally. Using the information given in the table below, state how long it will take for each ball to fall to the ground after being launched. Ignore air drag. Ball 1 Ball 2 Ball 3 Ball 4 Ball 5 0.2 18 (m/s) At...
please round 4 significant figures and show the formulas used o.) Assuming it lands at the same height it was launched at, determine how F FAST the projectile will be golng upon impsct E.) Assuming it lands at the same height it was launched at, determine the ANGLE (retative to the horizontal) of impaet. 10 points 2.D Kinematics: Word Problem #2 At what angle above the horizontal should a projectile be fired so that its range (x-displacement magnitude) is FIVE...
Exactly 3.1 s after a projectile is fired into the air from the ground, it is observed to have a velocity v⃗ = (9.0 i^ + 4.7 j^)m/s, where the x axis is horizontal and the y axis is positive upward. 1. Determine the horizontal range of the projectile 2. Determine its maximum height above the ground 3. Determine the speed of motion just before the projectile strikes the ground 4. Determine the angle of motion just before the projectile strikes...
A projectile is fired from level ground with an initial speed of 24.3 m/s at a launch angle of 32 degrees relative to the horizontal direction. Where does the projectile land if you ignore air resistance? (Assume 3 significant digits).^ (2)
A projectile is fired into the air from the top of a 200-m cliff above a valley. Its initial velocity is 60 m/s at 60° above the horizontal. (a) Where does the projectile land? (b) How long does the ball in air? (c) At what times velocity is 40m/s? I.
2. A projectile is fired from a cannon with initial velocity of 1000 m/s and at an angle of 30° from the horizontal. The point of impact is 1500 m below the point of release. (a) How long does it take for the projectile to hit the ground? (b) Find the projectile's speed at impact. (c) Find the horizontal range of the projectile. (d) Find the maximum height. Neglect air resistance. 1000 m/s 1500 m PREPARED BY: REVIEWED BY: NOTED...
7. Assuming there is negligible air resistance, what is the range of a projectile fired from ground level with a velocity of 30.0 m/s at an angle of 30° to the horizontal? 20 G
2) A projectile is launched into the air from ground level heading east. The projectile is launched at an angle of 45° with an initial velocity of 20 m/s. The wind is blowing the projectile in the north direction, with an acceleration of 2 m/s?. Assuming gravity is pulling the projectile downward toward the ground at a constant 9.8m/s", where does the projectile land in relation to its starting position?
