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.
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 tennis player hits a ball at ground level, giving it an initial velocity of 24 m/s at 57 degrees above the horizontal. (a) what are the horizontal and verticla components of the ball;s initial velocity? (b) how high above the ground does the ball go? (c) How long does it take the ball to reach its maximum height? (d) What are the ball;s velocity and acceleration at its highest point? (e) for how long a time is the ball...
in projectile motion problems where the projectile height h is modeled bythe equation h=-16t²+vt+s, where t is the time in seconds the objecthas been in the air, v is the initial vertical velocity in feet per second, and s isthe initial height in feet. The -16 coefficient in front of the t² term refers tothe effect of gravity on the object.A baseball field is next to a building that is 130 feet tall.A series of batters hit pitched balls into...
A tennis player hits a ball at ground level, giving it an initial velocity of 27.0 m/s at 59.0 ∘ above the horizontal. Part A.) What are the horizontal vh and vertical vv components of the ball's initial velocity? Part B.) How high above the ground does the ball go? Part C.) How long does it take the ball to reach its maximum height? Part D.) What is the ball's velocity at its highest point? Part E.) What is the...
Language: Python Create a program that determines how quickly an object is traveling when it hits the ground. The user will enter the height from which the object is dropped in meters (m). Because the object is dropped its initial speed is 0m/s. Assume that the acceleration due to gravity is 9.8m/s. You can use the formula vf =v^2i + 2ad to compute the final speed, vf, acceleration, a, and distance, d, are known.
a. An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s from a height of 1.55 m above the ground. Will the rock reach the top of the wall? If so, how fast is it moving when it reaches the top. If not, what initial speed must it have to reach the top? b. To defend the castle, a rock is thrown downwards from the top of the wall with...
A coin is tossed upward from an initial height of 7 m above the ground, with an initial speed of 7.4 m/s m/s. The magnitude of the gravitational acceleration g = 9.8 m/s2 Take the point of release to be y0 = 0. Choose UPWARD as positive y direction. Pay attention to the signs of position, velocity and acceleration. Keep 2 decimal places in all answers. (a) Find the coin’s maximum height in meters above the ground? m Correct (100.0%)...
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...
1. If a sky-diver jumps out of a plane, two forces will act on him, gravity and air resistance. If we assume air resistance is proportional to the velocity, we get the total force on the sky diver will be F = −gm − kv, where g is a acceleration due to gravity on the surface of the earth, m is the mass of the sky-diver, v is the velocity of the sky-diver, and k is constant of proportionality for...
