An object is being pushed up an inclined plane with a constant force F = 100. N. The plane makes an angle of 30.0° with respect to the horizontal. The object is moving with constant velocity. The coefficient of kinetic friction between the object and the surface is 0.300. What is the mass of the object?
Illustratr what is the amplitude of the oscillations? What were the (b) position and (c) velocity of the block at t = 0 s?
The spacecraft's mass is 291 kg and the thrust (force) of the rocket engines is 59 N. If the speed of the spacecraft should be decreased by 128 m/s, how long the engines should be fired. (Ignore the change in mass as a result of the rocket engines..
What is the wavelength of the light in the glass
assume a block of mass 25.0 kg rests on a horizontal plane, and the coefficient of static friction between the surfaces is 0.220. what is the actual static frictional force that acts on the block if an external force of 25.0 N acts horizontally on..
How much power must you exert to horizontally drag a 20.0 kg table 14.0 m across a brick floor in 40.0 s at constant velocity, assuming the coefficient of kinetic friction between table and floor is 0.550.
The partial pressures of gas A and gas B, respectively, are 0.238 atm and 0.779 atm. If 0.220 mol a third gas is added with no change in volume or temperature, what will the total pressure become?
A submarine dives 90.0 m at an angle of 8.0° below the horizontal. What are the horizontal and vertical components of submarine's displacement? (Imagine that upward and the direction of the submarine's horizontal motion is positive.)
A javelin is thrown at an initial speed of 28.5 m/s at an initial height of 1.93 m above the ground, Find this maximum range
A light plane is headed due south with a velocity of 157 km/h relative to still air. After 1.00 hour, the pilot notices that they have covered only 121 km and their direction is not south but southeast (45.0^circ).
What is the speed of the block of clay right after the collision. What impulse does the clay exert on the block.
A horizontal block-spring system with the block on a frictionless surface has total mechanical energy E = 49.2 J and a maximum displacement from equilibrium of 0.280 m.
At an outdoor market, a bunch of bananas attached to the bottom of a vertical spring of force constant 16.0 N/m is set into oscillatory motion with amplitude of 20.0 cm.
