Learning Goal: A box of mass 3.0 kg slides down a rough vertical wall. The gravitational force on the box is 29.4 N. When the box reaches a speed of 2.5 m/s, you start pushing on one edge of the box at a 45° angle (use degrees in your calculations throughout this problem) with a constant force of magnitude Fp = 23.0 N, as shown in ( Figure 1).

A 23 kg child goes down a straight slide inclined 38 degrees above horizontal. The child is acted on by his weight, the normal force from the slide, kinetic friction, and a horizontal rope exerting a 30 N force as shown in the figure(child is being pulled from rope going left to right ontop of slide). How large is the normal force of the slide on the child?

Good day Maam/Sir, I hope you can help me with this...... its all aboute Friction Force.... We have this simulation values: You will be starting with a crate that has a mass of 100 kg and a coefficient of sliding friction of 0.3 and a coefficient of static friction of 0.5 in 30 degrees. Question: Calculate how much force you would have to apply to the crate to get it to go at constant speed up the 30 o Show your work below and record your answer to the tenth of a Newton (Hint: Remember it’s moving now, so which μ do you need to use?)
