A celebrating student throws a water balloon horizontally from a window 50 m above the ground. It hits the ground 60 m from the building without appreciable air resistance. (a) What is the horizontal component of the velocity of the balloon just before it hits the ground? (b) What is the magnitude of the vertical velocity of the balloon just before it hits the ground?
A student drops a water balloon out of a dorm window 79 m above the ground. What is the speed in m/s when it hits the ground? Round to the closest whole number.
A student drops a water balloon out of a dorm window 16 m above the ground. What is its speed when it hits the ground?
A rock is at a height of 21.9 m above the ground and is thrown at 12.2 degrees below the horizontal. It hits the ground 49.5m horizontal from where it was thrown. A) what is the initial velocity of the rock? B) what is the final velocity of the rock?
A water balloon is launched
with an initial speed of 40 m/s at 60 degrees above the horizontal.
A tall building is 40 m from the launch site. Neglect air
resistance and use g = 10 m/s^2.
(numbers 8-11) A water balloon is launched with an initial speed of 40 m/s at 60 degrees above the horizontal. A tall building is 40 m from the launch site. Neglect air resistance and use g 10 m/s2 8. How much time does...
3. A water balloon is thrown vertically up with the initial velocity 20 m/s from a balcony 30 m above the ground. (a) What is maximum height above the ground the balloon will reach? (b) How much time will it take to reach the maximum height? (c) How much time will it take to reach the ground? (d) What is the balloon's velocity at the instant just before it hits the ground? (Be sure to include the correct signs)
A water balloon is launched at a speed of 34.0 m/s and an angle of 36 degrees above the horizontal. The water balloon hits a tall building located 23.0 m from the launch pad. At what height above the ground level will the water balloon hit the building? Calculate the answer in meters (m) and rounded to three significant figures.
A) If a water balloon is thrown straight up at 12 m/s from the top of a 13 m building, how long will it take to hit the ground? B) If a water balloon is thrown straight down at 14 m/s from the top of a 31 m building, how long will it take to hit the ground? C) If a water balloon is thrown upwards at a 17 degree angle at 14 m/s from the top of a 31...
A 124-kg balloon carrying a 22-kg basket is descending with a constant downward velocity of 19.8 m/s . A 1.0-kg stone is thrown from the basket with an initial velocity of 12.3 m/s perpendicular to the path of the descending balloon, as measured relative to a person at rest in the basket. That person sees the stone hit the ground 14.2 s after it was thrown. Assume that the balloon continues its downward descent with the same constant speed of...
A projectile is shot from the edge of a cliff 115 m above ground level with an initial speed of v0 = 56 m/s at an angle of 35.0∘ with the horizontal, as shown in the figure A-Determine the time taken by the projectile to hit point P at ground level. B-Determine the distance X of point P from the base of the vertical cliff. C-At the instant just before the projectile hits point P, find the horizontal and the...
