Draw a free body diagram for both parts of this question, also include the formulas Fnet=ma and Fnet = F1 + F1, and any other formulas used:
A large football player student (1.0 x 102 kg) applies a 6.0 x 102 N force to another equally burly student (1.0 x 102 kg) sitting on a sled (13.2 kg). If sliding friction and air resistance (drag) is 99.5 N, find the acceleration of the sled. In addition, how much force does the football player need to apply to the ground to accomplish this feat? Remember, he needs to get himself moving too!
At the instant the alpha particle leaves the nucleus, the centers of the two are 7.5 apart and essentially at rest. Find their speeds while they're a great distance apart. Treat each particle as a spherical charge distribution.
Two particles are fixed to an x axis: particle 1 of charge q1 = +1.00 10-8 C at x = 20 cm and particle 2 of charge q2 = -4.50q1 at x = 70 cm. At what coordinate on the axis is the net electric field produced
A singly ionized 24Mg ion (mass 3.983 10-26 kg) is accelerated through a 2.0 kV potential difference and deflected in a magnetic field of 500 G in a mass spectrometer. Find the radius of curvature of the orbit for the ion
A 2.28uF capacitor is charged to 1230V and a 7.87uF capacitor is charged to 530V. These capacitors are then disconnected from their batteries, What will be the potential difference across each
Suppose you have the following intermediate (i.e., important figures may be incorrectly stated) experimental results: L = 0.739 ± 0.026 m , f1 = 36.48 ± 1.82 Hz , T = 5.28 N (exact) . What is the linear mass density of the string (without uncertainty..
The block starts at the top of the wedge at 1.2 m. Find out the final speeds of a block and the wedge once the blook has slid to the bottom.
A gauge-12 wire has diameter centimeters and length meters. while the voltage volts is applied to the ends of the wire, the current is amperes. The concentration of free electrons in the wire is per cubic meter.
Your personal stereo is in a dead spot caused by direct reception from an FM radio station at 91.9MHz interfering with the signal reflecting off a wall behind you.How much farther from the wall should you move so that the interference is fully constr..
An LC circuit includes a 0.010 µF capacitor and a 400 µH inductor. If the peak voltage on the capacitor is 190 Volt, determine what is the peak current in the inductor
A particle known as a pion lives for a short time before breaking apart into other particles. According to this hypothetical person, how far does the laboratory move before the pion breaks apart
Consider the gas-solid equilibrium in the model when oscillators in the solid move in three dimensions. In the high temperature limit T>>hbarω find pressure P(T) as the function of temperature.
