A horizontal force, F1 = 95 N, and a force, F2 = 18.9 N acting at an angle of θ to the horizontal, are applied to a block of mass m = 2.9 kg. The coefficient of kinetic friction between the block and the surface is μk = 0.2. The block is moving to the right. Calculate the normal force when the angle is 30. and acceleration when the angle is 30.

The density of a substance is 4.0 g/cm3. if a sample of the substance has a volume of 25 cm3 then what is the mass

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)
