orces of 80 N at 130 degrees, and 10 N at an angle of 190 degrees, measured counter-clockwise from the positive x-axis, act on an object. What is the magnitude of the resultant force (in...

A ship sails 30 kilometers 70 degrees north of east. It then turns 110 degrees to the west, giving it a new heading of 0 degrees north of west. After sailing another 30 kilometers, how far is...

A ball is thrown upward at time t=0 from the ground with an initial velocity of 18 m/s (~ 40 mph). Assume that g = 10 m/s2. What is the greatest height (in meters) reached by the ball?

a sum related to atomic physics.......eV(electron volt)

Point A is at an electric potential of +75V and point B is at an electric potential at -75V. The work done by an external force to move a charge from A to B is 7.5 x 10-4 J. If the charge...

In outer space, a constant net force of magnitude 142 N is exerted on a 31.6 kg probe initially at rest.

The wave y1 = 0.12 sin π/3(5x+200t-1) propagates on a string of linear density 0.02 kg/m. (a) Calculate the average power transmitted. (b) If the wave y2 = 0.12 sin π /3(5x+200t+3)...

physics question

Having traveled the first 0.50 of the distance of your trip at an average speed of 30.0 km/hr, how fast must you travel for the rest of the trip in order to average 35.0 km/hr?

A helium-neon laswer produces light with a peak wavelength of 633 nm when at rest. Imagine that such a laser is being carried on a spaceship. If you observe light from the spaceship's laser to have...

A car starts from rest and travels for 7.0 s with a uniform acceleration of +2.4 m/s2. The driver then applies the brakes, causing a uniform acceleration of -1.0 m/s2. If the brakes are applied...
