You are trying to find out how high you have to pitch a water balloon in order for it to burst when it hits the ground. You discover that the balloon bursts when you have pitched it to a height of 19 m. With what velocity did the balloon hit the ground? The acceleration of gravity is 9.8 m/s 2 . The positive direction is up, so the velocity when it hits is negative. Answer in units of m/s.

You are trying to find out how high you have to pitch a water balloon in order for it to burst when it hits the ground. You discover that the balloon bursts when you have pitched it to a height of 14 m. With what velocity did the balloon hit the ground? The acceleration of gravity is 9.8 m/s 2 . Answer in units of m/s
A water balloon is shot into the air so that its height h, in metres, after t seconds is h = —4.9t^2 + 27t + 2.4 a)How high is the balloon after 1 s? b)For how long is the balloon more than 30 m high? c)What is the maximum height reached by the balloon? d)When will the balloon hit the ground?
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 124-kg balloon carrying a 22-kg basket is descending with a constant downward velocity of 16.4 m/s . A 1.0-kg stone is thrown from the basket with an initial velocity of 19.0 m/sperpendicular 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 17.3 s after it was thrown. Assume that the balloon continues its downward descent with the same constant speed of 16.4...
A balloon filled with water is dropped from a height of 20.0 m. At the same time, a dart is fired straight up from the ground below the balloon. The initial speed of the dart is 15.0 m/s. When does the dart hit the balloon and how high above the ground does the dart hit the balloon? Assuming that the balloon breaks instantaneously and that the dart doesn’t affect the motion of the water, how long after the balloon breaks...
Constants Part A A 124-kg balloon carrying a 22-kg basket is descending with a constant downward velocity of 16.4 m/s. A 1.0-kg stone is thrown from the basket with an initial velocity of 19.0 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 17.3 s after it was thrown. Assume that the balloon continues its downward descent with the same constant...
You throw your phone straight out horizontally so that is leaves your hand with a velocity of 15.6 m/s forward. When the phone leaves your hand, its vertical height is 1 m above the ground. Once it leaves your hand, it begins to fall while moving forward due to gravity pulling it downward. a. What is the phones initial velocity in the horizontal (forward) direction in the instant it leaves your hand? b. What is the phones initial velocity in...
part 1 of 3A tennis ball is dropped from 1.79 m above the ground. It rebounds to a height of 1.01 m. With what velocity does it hit the ground? The acceleration of gravity is 9.8 m/s2. (Let down be negative.) Answer in units of m/s. part 2 of 3 With what velocity does it leave the ground? Answer in units of m/s. part 3 of 3 If the tennis ball were in contact with the ground for 0.0126 s. find the acceleration given to the...
You are in a hot air balloon (yes, another balloon problem!) rising from the ground at a constant velocity of 2.20 m/s upward. To celebrate the takeoff, you open a bottle of champagne, expelling the cork with a horizontal velocity of 4.40 m/s relative to the balloon. When opened, the bottle is 6.40 m above the ground. (A)What is the initial speed of the cork, as seen by your friend on the ground? (B)What is the initial direction of the...
First you need to find the acceleration and then the time Please
explain how you get ( t ), which way you have used?. And why.
For
this I only have one question. Do we need to divide the distance r
1 cm by 100 to convert it to m in order to get the final answer? Or
just keep it as its.
Show all work clearly. No credit for answer only. Provide the proper units. 1. A particle of...
