A physics student of mass 59.0 kg is standing at the edge of the flat roof of a building, 12.0 m above the sidewalk. An unfriendly dog is running across the roof toward her. Next to her is a large wheel mounted on a horizontal axle at its center. The wheel, used to lift objects from the ground to the roof, has a light crank attached to it and a light rope wrapped around it; the free end of the...
Mr. Physics drops a rock down a 250-meter deep well. Upon impact with the bottom burst of sound is produced with a frequency of 250 Hz. How much time after he drops he hear it hit the bottom of the well. (Use GUESS method.) Answer 7.87 seconds the rock does
A sky diver drops his smuggled 1kg weight from physics lab out of the air plane before he jumps, which is flying horizontally going 175 m/s at a height of 2 km. IF WE ASSUME NO AIR RESISTANCE, what is the Velocity (magnitude and direction) when it hits the ground? If an object initially at rest is given a velocity of: V-1.93 m/s and vy 2.51 m/s. What is the magnitude and direction its displacement after a time of 3.50...
a student has climbed on the roof of a building and is trying to hit her friend with snowballs as he walks through the quad. she throws them at an angle 20 degrees above the horizontal at a speed 5m/s. the building has height h = 6m. how much time does it take for the snowballs to hit the quad ? where do the snowballs land on the quad ? how fast are the snowballs traveling when they hit the...
A student drops two ball bearings, a lighter one and a heavier one, from a top of a roof. The friction is insignificant. Just before hitting the ground, the heavier ball has twice the kinetic energy. How much faster did it go? so to do this I just did. KE = 1/2 m V^2 2KE = mv^2 so 0.5 faster?
C++ Programming Windows Application Console Student Generated Problem Option 2.5 Option 2.5: Suppose Dave drops a watermelon off a high bridge and lets it fall until it hits the water. If we neglect air resistance, then the distance d in meters fallen by the watermelon after t seconds is d 0.5 g* t where the acceleration of gravity 9.8 meters/second?. Write a program that asks the user to input the number of seconds that the watermelon falls and the height...
Projectile Motion Problems for Student Practice Physics C Free Response Option #3 A projectile is launched from a level plane toward a 65 m high cliff. The cliff is 150 m away from the cannon. At launch, the projectile has a velocity of 80 m/s at an angle 55 above the horizontal. Air resistance is negligible. a) Draw a repeesentation of the trajectory of the peojectile (for this one, do this after you find out where it hits) b) Calculate...
1t A student is building a model roller coaster. The car rolls down from a standing start at the top of the first hill, which is 2 m high. The car fails to make it up to the top of the second hill, which is 2.1 m high. Ignoring friction and air resistance, which is MOST LIKELY the source of the problem? A. The car has too much mass B. The second hill is higher than the first * C....
Hi, may I get some help with explanation? Thank you Problem 3 A physics student is sitting on a rotating platform. He is holding a heavy weight in each of his outstretched hands. At request of his physics instructor(!) he carries out various manoeuvres to try to change his angular velocity. Which of the following scenarios are described correctly? Select True or False. Starting with angular velocity wow he raises his feet, and points them outwards from the chair as...
