A hot air balloon decends toward the ground with a velocity of (1.6 m/s). A champagne bottle is opened to celebrate takeoff, expelling the cork horizontally with a velocity of (4.0 m/s) relative to the balloon. When opened, the bottle is 6.2 m above the ground. (Neglect air resistance.) (a) What is the initial velocity of the cork, as seen by an observer on the ground? = ( m/s) + ( m/s) (b) What is the speed of the cork, and its initial direction of motion, as seen by the same observer? Speed m/s Direction ° below the horizontal (c) Determine the maximum height above the ground attained by the cork. m (d) How long does the cork remain in the air?
A satellite revolves around a planet at an altitude equal to the radius of the planet. The force of gravitational interaction between the satellite and the planet is F_0. Then the satellite moves to a different orbit, so that its altitude is tripl..
A speeding motorist traveling 105km/h passes a stationary police officer. The officer immediately begins pursuit at a constant acceleration of 12km/h/s (note the mixed units).
An MP3 player operates with a voltage of 3.7 V, and is using 0.28 W of power. Find the current being supplied by the player's battery.
Objects A and B are both positively charged. Both have a mass of 400g , but A has twice the charge of B. When A and B are placed 25cm apart, B experiences an electric force of 0.54N . What is the charge on A? If the objects are released, what is t..
The power is off for 34.0 s and throughout this time the flywheel slows as a result of friction in its axle bearings. Throughout the time the power is off, the flywheel makes 180 complete revolutions.
A resistor with an unknown resistance is connected in parallel to a 12 ohm resistor. while both resistors are connected to an emf source of 12 V, current across the unknow resistor is measured with an ammeter to be 3.0 A. What is the resistance of..
An object, at the top of a very tall building, is released from rest and falls freely due to gravity. Neglect air resistance and calculate the distance covered by the object between times t1 = 5.57 s and t2 = 7.59 s after it is released.
A parallel-plate air capacitor with a capacitance of 245 has the charge of magnitude 0.1502 on each plate. The plates have the separation of 0.323.
What are speed and direction of the ball after the collision
An proton (m = 1.67 ´ 10-27 kg and q = 1.6 ´ 10-19 C) travelling at 2.7 × 105 ms-1 enters a magnetic field of 1.2 T at right angles to the direction of motion of the electron. What is the centripetal force on proton.
