3. A person with a mass, m 100 kg is standing on a scale calibrated in Newtons inside a completely enclosed tank with negligible mass. The tank is placed on a fixed, frictionless inclined plane. A force, F 290 N is directed up the incline as shown. The tank is released from rest and begins to accelerate. Inside the enclosed tank, the person on the scale has no knowledge of the inclined plane or the force, F 30° e Wlis...

Figure 1: Block on incline. 2, A block of mass m = 5 kg is subject to a force of magnitude 20 N that makes an angle of p20 with the (frictionless) inclined plane of contact. The plane itself is inclined θ = 300 with the horizontal. (a) What is the acceleration of the block along the incline? (b) If the block begins at rest, in what direction will it move subsequently (i.e., up or down the incline)? (c) If...
