- Two forces F1 = (55.6i - 26.83j) N and F2 = (27.41i - 80.52j) N are exerted on a particle. The particle's mass is 10.14 kg. (a) Find the particle's acceleration in component form (express your answer in vector form). (b) what are the magnitude (m/s2) and direction of the acceleration (counterclockwise from the +x axis). Use four decimal places.3 of 5 т 1. Consider a container, of mass 66.4 kg, sitting on a steep ramp as shown. The angle of the ramp is 48.3 °. The coefficient of static friction between the ramp and the container is 0.80 (which is pretty sticky). If nothing else is acting on the container (figure A), will the container slide (a) down the ramp? (Explain how you know, don't just say yes or no!) (b) move up the ramp? How hard do you have to push on the container (figure B) in order to get it toA block with mass mb=7.75 kg is suspended on a string. You pull upwards on the string creating a tension force of magnitude TYb=79.2275 N. If the upward speed of the block is 2.25 m/s right now, then what is its speed 5.5 s later?
- Two forces FA and FB are applied to an object whose mass is 10.2 kg. The larger force is FA. When both forces point due east, the object's acceleration has a magnitude of 0.483 m/s². However, when FA points due east and FB points due west, the acceleration is 0.389 m/s², due east. Find (a) the magnitude of FA and (b) the magnitude of FB.
