Q. A hiker begins a trip by first walking 24.1 km southeast from her base camp. On the second day, she walks 46.8 km in a direction 65.9 degrees north of east, at which point she discovers a forest ranger's tower. Determine the y component of the total displacement and magnitude of the resultant displacement.
Q. A 7-kg projectile is fired with an initial speed of 137 m/s at an angle of 34° with the horizontal. At the top of its trajectory, the projectile explodes into two fragments of masses 2.6 kg and 4.4 kg. At 4.1 s after the explosion, the 4.4-kg fragment lands on the ground directly below the point of explosion.
(a) Determine the magnitude of the velocity of the 2.6-kg fragment immediately after the explosion.
(b) Find the distance between the point of firing and the point at which the 2.6-kg fragment strikes the ground.
A 3.2 kg block of wood sits on a table. A 3g bullet, fired horizontally at a speed of 490 m/s, goes completely through the block, emerging at a speed of 250m/s. What is the speed of the block immediately after the bullet exits.
A hydraulic lift consists of two pistons that connect to each other by an incompressible fluid. If one piston has an area of 0.49 m^2 and the other an area of 6.2m^2, how big a mass can be raised by a force of 220N exerted on the smaller piston.
An old hunting weapon was a rock on the end of a string. The hunter would swing the rock in horzontal circles and then throw it. If the rock had a mass of 2 kg and the 2 m long string breaks when the tension is 60N.
How numerous extra electrons are on this particular oil drop (given the presently known charge of the electron)?
Carry out the following arithmetic operations: (a) sum of the measured values 756, 37.2, 0.83 and 2.5. The answer must be in significant digits. Since 2.5 and 0.83 have two significant digits, shouldn't the answer be 800 instead of 797.
According to the law of universal gravitation, what will happen to Earth if the Sun were somehow replaced by the black hole of same mass.
Assume you are the fish. You get up every morning and weigh yourself (in water), and find you weigh 0.42 N. You, being a boxfish, are a box measuring 4.164 cm per side. You see a poor, hungry fisherman, and decide to be his dinner. You hook yourself,..
while the other terminal of the ammeter is connected to the other wire, ammeter shows that the current through the wire is 1 A. You then disconnect everything and travel to the other end of the telephone line, where you repeat the process and find ..
Find out distance the two drivers travel
from the scattering of sunlight, J. J. Thomson calculated the classical radius of an electron as having the value 2.82 ×10-15 m. Sunlight with an intensity of 500 W/m2 falls on a disk with this radius.
What is magnitude of the linear acceleration of the hoop . Elucidate using Newton's Second Law of Motion, why you can throw a golf ball further than a bowling ball, still though you throw both at the similar angle and with the same amount of force.
A screen is placed 51.0 cm from a single slit that is illuminated with light of wavelength 677 nm. If the distance between the first and third minima in the diffraction pattern is 2.80 mm, what is the width of slit.
