Q. The tallest volcano in the solar system is the 22km tall Martian volcano, Olympus Mons. An astronaut drops a ball off the rim of the crater and that the free fall acceleration of the ball remains constant throughout the ball's 22km fall at a value of 3.6 m/s2. (We assume that the crater is as deep as the volcano is tall, which is not usually case in nature.)
Find out the time for the ball to reach crater floor.
A crate with mass 35.5 initially at rest on a warehouse floor is acted on by a net horizontal force of 120. What acceleration is produced.
Find the electric field strength from the wire. How long is each spring when hanging as shown.
Suppose that the air bubble is always in thermal equilibrium with the surrounding water.
You're carrying a 3.2-m-long, 25 pole to construction site when you decide to stop for a rest. You place one end of the pole on a fence post and hold the other end of the pole 35 from its tip. How much force must you exert to keep the pole motionl..
A force F = 200i - 400j + FZ k N, is acting through point A(0,0,0) m.
Now the gymnast (not holding any additional mass) walks directly above right support. What is the force the left support exerts on beam.
Determine the net charge contained within the cube.
What mass can it support in water before sinking. Two concentric spherical shells with uniformly distributed masses M1 = kg and M2 = kg are situated as shown . Find out the magnitude Find the magnitude of the net gravitational force on a particle ..
A hot (70°C) lump of metal has a mass of 250g and a specific heat of 0.25 cal/g°C. John drops the metal into a 500 g calorimeter containing 75g of water at 20°C.
A wheel has a radius of 3.6m. How far (path length) does a point on the circumference travel if the wheel is rotated by angles of 30°, 30 rad, and 30 rev, respectively.
Find an average magnitude of the induced emf . A bungee jumper, who's mass is 79 kg, jumps from a tall building. After reaching his lowest point, he continues to oscillate up and down, reaching the low point two more times in 8.2 s.
Assume that, as lying on a beach near the equator watching the Sun set over a calm ocean, you start a stopwatch just as the top of the Sun disappears. You after that stand, elevating your eyes by a height H = 1.90 m.
