1. Force P is necessary to drag the crate shown in Fig. below at constant velocity, the crate weighs 500 N, and coefficient of kinetic friction is = 1.0. (A) Calculate the normal force on the crate. (B) Calculate magnitude of force P AIRLINE BAGGAGE P DANGER 130.0 2. Find the acceleration of the 5.0 kg block in the fig below: 4.0 kg 2.0 kg H=,=0.10 5.0 kg 3. An object of mass m = 1 kg is initially placed on a frictionless plane, inclined by an angle 0 = 30 as indicated below. How long does it take the mass to move the distance of 10 m down the incline? Show your work clearly. 30 1 kg 4. An 8 kg block is placed at the top of a plane inclined by 30 angle. The coefficient of kinetic friction between the block and the plane is 0.1. Determine the block's acceleration down the ramp. Show your work clearly. 5. mi (cart plus box) sits on a frictionless surface and is accelerated to the right as m2 falls. Assume that m = 0.340kg and m2 = 0.150 kg, respond to the following questions. a) Calculate the acceleration of the masses. Show your work clearly. b) Calculate tension force in the thread. Show your work clearly.
