Q. A person in an elevator is holding a 25 kg block by a cord rated to withstand a tension of 335 N. Starting from rest, the elevator begins to move upwards at a constant acceleration and the cord holding the block breaks. What was the minimum acceleration of the elevator? Assume g = 10 m/s2
Q. A subway train rounds an unbanked curve at 70 . A passenger hanging onto a strap notices that an adjacent unused strap makes an angle of 14 to the vertical. What is the radius of the turn?
Coherent light with wavelength 546 nm passes through two very narrow slits, and the interference pattern is observed on a screen the distance of 3.00 {rm m} from the slits. The first-order bright fringe is a distance of 4.86 {rm mm} from the center o..
For a real train the friction between the car and the track can be described by a friction coefficient, μ. Find out this coefficient assuming that the time it takes for the car to come to rest is 3 s.
Regarding the Earth and a cloud layer 750 m above the Earth as the "plates" of a capacitor, calculate the capacitance. Assume the cloud layer has an area of 1 km2 and that the air between cloud and ground is pure and dry.
As part of a safety investigation, two 1900 cars traveling at 25 are crashed into different barriers. Find out the average forces exerted on (a) car that hits a line of water barrels and takes 1.8 to stop, and (b) car that hits a concrete barrier an..

A pitcher throws a fastball horizontally at a speed of 150 km/h toward home plate, 18.4m away. If the batters combined reaction and swing times total 0.37s, how long can batter watch the ball after it has left the pitcher's hand before swinging? In t..
A charge of 3.80 10-6 C is placed on a small conducting sphere that is located at the end of thin insulating rod whose length is 0.22 m. The rod rotates with an angular speed of ω = 156 rad/s about an axis that passes perpendicularly through its o..
A 106 m long train begins uniform acceleration from rest. The front of the train has a speed of 23 m/s when it passes a railway worker who is standing 230 m from where the front of train started. What will be the speed of last car as it passes the..
what is the frequency of vibration of the string. If the shot was launched from 6.00 f above the ground at an initial angle of 42.0 degrees , what was its initial speed.
A small, 300 {rm g} cart is moving at 1.30 {rm m/s} on an air track when it collides with a larger, 3.00 {rm kg} cart at rest. After the collision, the small cart recoils at 0.890 {rm m/s}.
In response to a stimulus, membrane can become permeable to Na ions. As Na ions rush into the cell, the interior of the cell reaches an electric potential of about 40 rm mV.
