A 2.5-kg block slides down a 17.0° inclined plane with constant acceleration. The block starts from rest at the top. At the bottom its velocity reaches 0.70 m/s. The length of the incline is 1.7 m. What is the acceleration of the block? What is the coefficient of friction ...

Two horizontal parallel wires which carry currents I1 = 45 A (top)and I2 (bottom). The top wire is held in position, the bottom wire is prevented from moving sideways but can slide up and down without friction. If the wires have a mass of 9.2 g per metre of length, calculate ...

A of car of mass 2000 kg has a force forward due to the engine of 4500N and experiences an air resistance of 1500N. IF we ignore the friction with the road, what is the acceleration of this car? thanx :)
