A 2.00 kg(m;) block is initially at rest on an inclined surface at angle 0= 40.0° and is connected to a free-hanging 5.00 kg mass by a stretchless, massless cord that passes over a small frictionless pulley. (g=9.81 m/s²). At time 0.00 sec, the system is released. m2 Calculate the magnitude of the acceleration of the two-block system if we assume that the inclined surface is frictionless. Which direction will m2 be moving (upwards or downwards)? O 6.297 m/s^2 5.20 m/s^2 22.04 m/s^2 2.546 m/s^2

Part A A block lies on a plane raised an angle e fram the horizantal. Three forces act upon the block: Fw, the force of gravity. Fn. the narmal force; and Fr. the force of friction. The coefficient of friction is large enaugh to prevent the block from sliding (Figure 1). Consider coordinate system a, with the x axis along e plane. Which forces lie along the axes?

O řr and Fa and Ě, Submit Request Answer Usually the best advice is to choose a coordinate system so that the acceleration of the system is directly along one of the coordinate axes. If the system isn't accelerating, then you are better off choosing the coordinate system with the most vectors along the coordinate axes. But now you are gaing to ignore that advice.…

A 30 kg cannonball is shot at a sailing ship. When it hits the wooden sides of the ship, it just barely punches through the wooden hull, applying a 200 000 N force to the ship the whole time it was stopping. → If the cannonball was originally travelling at 300m/s, how long would it take to completely stop in the hull of the ship assuming constant acceleration.

A 800 kg cart is rolling to the right at 1.10 m/s. A 70.0 kg man is standing on the right end of the cart. Part A What is the speed of the cart if the man suddenly starts running to the left with a speed of 8.00 m/s relative to the cart?
