PHYSICS HELP PLEASE
The spring constant of a toy dart gun is 4442 N=m. To!@#$%^& the gun the spring is compressed 1.5 cm. The 8 g dart, fired straight upward, reaches a maximum height of 26 m. The acceleration of gravity is 9.81 m/s2 : Determine the magnitude of the energy dissipated by air ...

PHYSICS HELP PLEASE!!!
A block of mass 2.62 kg is kept at rest as it compresses a horizontal massless spring(k = 141 N=m) by 15.3 cm. As the block is released, it travels 0.627 m on a rough hori- zontal surface before stopping. The acceleration of gravity is 9.8 m/s2 :Calculate the coe±cient ...

physics helppp!
The coeffcient of friction between the 7.9 kg mass and the table is 0.55, and the coeffcient of friction between the 5 kg mass and the table is 0.38. Consider the motion of the 37 kg mass which descends by the amount of y = 0.45m after releasing the system from rest. The ...

physics help please
The two blocks are connected by a light string that passes over a frictionless pulley with a negligible mass. The 3 kg block lies on a rough horizontal surface with a constant coefficient of kinetic friction 0:3. The hanging block has a mass of 8 kg. The system starts from ...
