A 10 gram bullet is fired horizontally with a speed of 155 m/s into a 0.3 kilogram block that is initially at rest at the edge of a table with a height of 1.225 meter (above the ground). If the bullet remains in the block after the impact, obtain the horizontal distance the block will traverse before landing on the ground.
A car wheel with a moment of inertia of 7.85 kg.m^2 is accelerating from 2160 rpm to 5040 rpm in a time of 10.0s. calculate The work done in raising the rotation frequency
A gremlin is a tiny mythical creature often blamed for mechanical failures. Suppose for a moment that a shrewd physicist catches one such gremlin and makes it work for her instead of against her.
Find the magnitude of the acceleration a of a block as it slides down the incline without friction. You must use a coordinate system with horizontal x and vertical y
(a) A 5.00-µF capacitor is connected to a 15.0-V battery. How much energy is stored in the capacitor? (b) Had the capacitor been connected to a 6.00-V battery, how much energy would have been stored?
A balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. Assume that the stretching of the hose obeys Hooke's law with a spring constant of 53.0 N/m.
A bat (see the image below) can detect very small objects, such as an insect whose length is approximately equal to one wavelength of the sound the bat makes. what is the smallest insect the bat can detect
A boat takes 3.30 hours to travel 40.0 km down a river, then 5.00 hours to return. How fast is the river flowing
a stone is projected at a cliff of height h with an initial speed of 44.0 m/s directed at an angle θ0 = 62.0° above the horizontal. find the height h of the cliff
A bullet is fired through a board 13.5 cm thick, with a line of motion perpendicular to the face of the board. If the bullet enters with a speed of 387 m/s and emerges with a speed of 163 m/s, what is its acceleration as it passes through the boar..
A penny is located 14.5 centimeter from the center of a turntable. Find coefficient of static friction between penny and turntable
A parallel-plate air capacitor has a capacitance of 500 pF and a charge of magnitude 0.150 mu C on each plate. What is the surface charge density on each plate
The moon in its orbital about the earth has a centripetal acceleration about 1/4200 of that an object dropped on Earth's surface. If the moon were twice as far away what would its centripetal acceleration be?
