PHY 203 Introduction to Physics NAME:(17.1) A block of mass M = 20 kg rides on a frictionless horizontal plane surface whichwe choose to describe as the xy-plane. The z-direction is vertical, perpendicular to thexy-plane, with positive z pointing upward. At t = 0 , two constant applied forces,→F1 = 8 , 4 , 10N and →F2 = 12 , 6 , 10Nsuddenly begin to act. Take g = 10 m/s2for the weight force.(a) (i) Draw a free-body diagram, looking edge on to the plane, showing clearly the forceswhich act on the block in the vertical direction.(ii) Draw a free-body diagram, looking down on the plane, showing clearly the forceswhich act on the block in the horizontal direction.(b) Express each of the forces acting on the block in terms of its Cartesian components(in the directions specified by x, y, and z). [Hint: If you do not know the magnitude ofthe vector, but you do know its direction, then use a symbol – for the time being – for themagnitude.](c) Sum the forces to obtain the three components of…

David throws a 50 kg cart down a ramp with an initial speed of vi = 6 m/s. The ramp is at an angle of 20◦, and the coefficient of kinetic friction between the cart and the ramp is µk = 0.25. Additionally, the coefficient of static friction is µs = 0.55. How much time does it take to reach Ryan who is 10 m away? Assume that the cart slides and doesn’t roll.
John is building a frictionless track with a block (? = 20.0kg) sliding on it (no flying up). The block is initially at rest at point A, and it is pulled by an external force ? = 60.0N (with an angle ? = 25.0 ° from the surface of the track) over a distance ? = 3.50 to point B. There are no external forces on the block after point B and the block continues to slide along the track until the magnitude of its velocity is ?C = 0.700m/s at point C. What is the height ℎ of point C (relative to point A)?

A freight train consists of two 8.00×104 kg engines and 45 cars with average masses of 5.60×104 kg. (a) What force ( in N) must each engine exert backward on the track to accelerate the train at a rate of 4.00×10−2 m/s2 if the force of friction is 6.20×105 N, assuming the engines exert identical forces? This is not a large frictional force for such a massive system. Rolling friction for trains is small, and consequently trains are very energy-efficient transportation systems. answer= N (b) What is the force ( in N) in the coupling between the 37th and 38th cars (this is the force each exerts on the other), assuming all cars have the same mass and that friction is evenly distributed among all of the cars and engines? answer = N
