On a pleasure cruise a boat is traveling relative to the water at a speed of 5.33 m/s due south. Relative to the boat, a passenger walks toward the back of the boat at a speed of 1.16 m/s.
(a) What is the magnitude of the passenger's velocity relative to the water?
(b) How long does it take for the passenger to walk a distance of 34.3 m on the boat?
(c) How long does it take for the passenger to cover a distance of 34.3 m on the water?
The length of a simple pendulum is 0.73m, the pendulum bob has a mass of 307 grams, and it is released at an angle of 12° to the vertical. With what frequency does it vibrate? Assume SHM. What is the pendulum bob's speed while it passes through th..
Calculate the shear stress of the crude oil at the walls, and plotting the velocity distribution graph for the same.
A thick-walled hollow cylinder (inner radius=47 cm, outer radius=66 cm) rolls down a 7° incline. If it starts with a speed of 1.9-m/s, what is its speed after it has travelled 16 m? (m/s).
Find out the dividends per share for preferred and common stock for each year. Prepare a brief memo (no more than 120 words) giving the arguments for and against offering this preferred stock. In the memo also briefly mention other methods of obtai..
Once a traffic light turns green, a car speeds up from rest to 50 mi/h with constant acceleration 9 mi/h • s. In the adjoining bike lane, a cyclist speeds up from rest to 20mi/h with constant acceleration 13mi/h.
A space traveller whose mass is 115 kg leaves earth. What are his weight and masson earth and in interplanetary space where there are no nearby planetary objects.
A 280 g block on a 50.00 cm-long string swings in a circle on a horizontal, frictionless table at 70 rpm.
What is the speed of the arrow as it leaves the bow. At a height of 5 meters above the surface of a lake, a sound pulse is generated. The echo from the bottom of the lake returns to point of origin 0.130 s later. The air and water temperatures are ..
A woman inside an elevator is standing on a scale. Before the elevator starts moving the scale shows 50 kg, calculate the acceleration of the elevator if after the elevator starts moving upward the scale reads 70kg. What will the reading of the sc..
A neutron star has a mass of 2.20 × 10^30 kg (about the mass of our sun) and a radius of 5.20 × 10^3 m. Assume an object falls from rest near the surface of such a star. How fast would it be moving after it had fallen a distance of 0.0083 m.
State the maximum height in terms of a, t_1, and/or g. Note that in this problem, g is a positive number equal to the magnitude of the acceleration due to gravity.
