Two blocks (A and B) are in contact on a horizontal frictionless surface. A 40N constant horizontal force is applied to A. The mass of A is 5.0kg and the mass of B is 20kg. What is the magnitude of the force of A on B?
Guess scale factor of the Universe
The entrepreneur who founded the company is convinced that sales will increase next year by 150% and that net operating income will increase by 400%, with no increase in average operating assets. Illustrate what would be the company's ROI?
An aluminum cup of mass 200 g contains 800 g of water in thermal equlibrium at 80.0c. the combination of cup and water is cooled unformly so that temperature decreases by 1.50c per minute. at what rate is energy being removed by heat.
Discover the magnitude of acceleration
Note down that since each oscillator is attached to two "springs", and each "spring" is half the length of the interatomic bond, the effective interatomic spring stiffness for one of these oscillators is times estimated value given above.
Lonnie pitches a baseball of mass .20 kg. The ball arrives at home plate with a speed of 40 m/s and is batted straight back to Lonnie with a return speed of 60-m/s. If the bat is in contact with the ball for .050 s, what is the impulse experienced..
what is the max number of steps any worker should be allowed.
What is work done by the non-conservative force
find out the magnitude of their acceleration. If the blocks move determine the magnitude of the tension in the string. If the blocks do not move determine the sum of magnitude of the forces of friction acting on the blocks. Show all the work.
if the mass of the diver is 134kg and the board is 9m long, illustrate what is the torque due to gravity on the diving board with a pivot point at the fixed end of the board?
The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches the base. Evaluate how far does he slide?
A 16 kg steel ball is launched from a cannon at an angle of 20 degrees above the horizontal. The cannon exerted an average force of 1200 Newtons on the ball during launch. Now that ball is in the air and has almost reached its target, what is the ..
