Q1. An airplane is flying with a velocity of 93.0 at an angle of 24.0 above the horizontal. When the plane is a distance 111 straight above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from the dog will the suitcase land? You can ignore air resistance.
Q2. A block has an initial speed V(o) > 0 on a linear trajectory on the surface with friction coefficient u and air resistance (F = cv^2). Derive an equation that will represent the velocity (V) as a function of the position of the block (x). So V(x).
Compute the magnetic flux
What are magnitude and direction of net electrostatic force
At one instant a bicyclist is 28.0 m due east of a park's flagpole, going due south with a speed of 11.0 m/s. Then 24.0 s later, the cyclist is 26.0 m due north of the flagpole, going due east with a speed of 11.0 m/s. For the cyclist in this 24.0 s ..
A 10.0g bullet is fired horizontally into a 101g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 141 N/m. The bullet becomes embedded in the block. If bullet-block system co..
If the spring is stretched by 1.4 times the value in part A, and then released from rest, and the coefficient of kinetic friction between the box and the plank is 0.34, what is the magnitude of the initial acceleration of block as it starts moving..
The coefficients of friction for plastic on wood are μs = 0.50 and μk = 0.40. How much horizontal force would you want to apply to a 4.0-lb plastic calculator to start it moving from rest.
A cosmic-ray proton in interstellar space has an energy of 17.0 MeV and executes a circular orbit having a radius equal to that of Jupiter's orbit around the Sun (7.78 x 10^11 m). What is the magnetic field in that region of space.
You work for a moving company and are given the job of moving two crates (masses are 130kg and 280kg) held together by a rope attached between the two. You pull on a rope attached to the larger crate giving the system the acceleration of 0.29m/s2. Wh..
An airplane must reach a speed of 172 mi/h to take off. If the runway is 470 m long, what is the minimum value of the acceleration that would allow the airplane to take off productively.
How long does it take for the grinding wheel to stop ? Through how many radians has the wheel turned during the interval found in.
Establish steady-state electric field inside Nichrome wire
The mass per unit length of the cord is 1.24 e-2 kg/m, so the mass of the cord is negligible compared to the mass of block. The cord is being vibrated at a frequency of 167 Hz (vibration source not shown in the drawing).
