A 120g ball moving at 0.50 m/s in the + x direction is subject to a 0.25 N force in the - y direction for 2.5 s.
Find the change in magnitude of the balls momentum.
Find the balls final speed.
Find the angle between the balls final velocity and the positive x direction.
One mole of a monatomic gass initially at 273 K and 1 atm is compressed isothermally (T constant) from volume 22.4 L to 11. 4 L, Find the final pressure and draw a PV diagram, Labeling the initial and final states 1 and 2
A 275 ball is tied to a string. It is pulled to an angle of 4 and released to swing as a pendulum. A student with a stopwatch finds that 17 oscillations take 20.
When the door is open and at rest, the door closer exerts a torque of 5.40 NxM. What is the least force that you need to be relevant to the door to hold it open.
You throw a stone vertically upward with an initial speed of 6.0 m/s from a third-story office window, Find the time the stone is in flight
Determine out the work completed to move the particle from x = 0 to x_3 = 10.5 m graphically by determining the area under the F_x vs. x graph.
A highway curve has a radius of 125 m. At what angle should the road be banked so that a car traveling at 27.4 m/s has no tendency to skid sideways on the road.Find an acceleration of box and ramp.
If the two halves of the log only separate by a distance of 0.05m while the wedge travels 0.2m into the log, how much force is the wedge exerting on the two halves of the log to rip them apart.
What are the size and direction of the change in velocity if the initial velocity is 6 m/s south and the final velocity is 2 m/s west?
what are the magnitude and direction of its acceleration. A potential difference of 80 mV exists between the inner and outer surfaces of the cell membrane. The inner surface is negative relative to the outer surface. How much work is required to ej..
The bar is held by a cord that makes a 90? angle with respect to bar and 50 ? with respect to wall. Illustrate what is the magnitude of the horizontal force Hx on the pivot? The acceleration of gravity is 9.8 m/s2.
A train 450 m long is moving on a straight track with a speed of 82.1 km/h. The engineer applies the brakes at a crossing, and later the last car passes the crossing with a speed of 16.7 km/h. Assuming constant acceleration, determine how long the..
The solar wind is a thin, hot gas given off by the sun. Charged particles in this gas enter the magnetic field of the earth and can experience a magnetic force, calculate the radius of the circular path on which the particle would move if it were a..
