Consider an object on an incline where friction is present. The angle between the incline and the horizontal is ? and the coefficient of kinetic friction is ?k.
Part (a) Find an expression for the acceleration of this object. Treat down the incline as the positive direction.
What is the kinetic energy
An object whose weight is 100 Ibf experiences a decrease in kinetic energy of 500 ft. Ibf and an increase in potential energy of 1600 ft. Ibf. The initial velocity and elevation of the object, each relative to surface of the earth, are 50 ft/s and 40..
How far south of his starting point will he reach the opposite bank.
A metallic sphere has a charge of +3.7 nC. A negatively charged rod has a charge of -6.0 nC. When the rod touches the sphere, 7.2 109 electrons are transferred. What are the charges of the sphere and the rod now?
Compute the average number of ion pairs produced along the entire paths of 12.0 MeV electrons that are brought to rest in air. Would number of ion pairs produced in soft tissue be significantly different.
A 2.5-cm-tall object is 24cm to the left of a lens with a focal length of 12cm, Calculate the distance between image and the second lens
Current passes through a solution of sodium chloride. in 1.00 secnds, 2.68 x 10^16 Na+ ions arrive at the negative electrode, what is the current in the fluid
Her speed when she is above the bar is 1.3 m/s. Neglect air resistance, as well as any energy absorbed by the pole, and find out her altitude as she crosses the bar.
The maximum distance from Earth to the Sun (at our aphelion) is 1.521 x 10^11 m and the distance of closest approach (at perihelion) is 1.471 x 10 ^11 m. Assume the Earth's orbital speed at perihelion is 3.027 x 10 ^ 4 m/s. (overlook the effect of th..
What is the volume of the bubble when it reaches just below the surface of the lake, where temperature is 20°C.
At t = 0 a grinding wheel has an angular velocity of 23.0 rad/s. It has a constant angular acceleration of 31.0 rad/s2 until a circuit breaker trips at t = 2.00 s. From then on, it turns by 432 rad as it coasts to a stop at constant angular accele..
An electron with kinetic energy of 6.0 x 10-16 J is moving to the right along the axis of a cathode-ray tube. There is an electric field vector = (2.0 x 104 N/C) j in the region between the deflection plates.
