Q. Calculate the horizontal force that must be applied to produce an acceleration of 1.5 g for a 1.5 kg puck on a horizontal friction-free air table.
Q. what must be done to increase the velocity of a rocket traveling in space from 32,000 km per hour to 40,000 km per hour.
Two charged spheres are 8.45 cm apart. They are moved and the force on each of them is found to have been tripled. How far apart are they now.
A box weighing 300N is shoved across the floor of an apartment by a force of 400 N exerted downward at an angle of 35.2° below the horizontal. If the coefficient of kinetic friction between the box and the floor is 0.540, how long does it take to mov..
A car accelerates from rest to a kinetic energy of 2.06 x 105 J in a distance of 638 m. How much force did the car's engine deliver to produce this acceleration.
A 2.5 mol sample of helium gas initially at 300 K and 0.400 atm is compressed isothermally to 1.30 atm. Note down that the helium behaves as an ideal gas.
A glass window pane is exactly 20 cm by 36 cm at 10oC. By how much has its area increased as it temperature is 33oC, assuming that it can expand freely? Take the coefficient of thermal expansion for the glass to be exactly 9 x 10-6/Co.
When in deep space, the block accelerates at 4.2 m/s^2 even as a 120 N force is applied to it. The coefficient of static friction for a particular plane and this block is 0.31. What angle can this plane make with horizontal before the object starts t..
