If the coefficient of static friction between your coffee cup and the horizontal dashboard of your car is mus = 0.840, how fast can you drive on a horizontal roadways around a right turn of radius 25.0 m before the cup starts to slide? Vector A has a magnitude of 4.50 units, and vector B has a magnitude of 8.46 units. The two vectors make an angle of 52.0degree with each other. Find A middot B. A force F = (8i^ ? 3j^)N acts on a particle that undergoes a displacement deltar = (4i^ + j^)m. Find the work done by the force on the particle. (Calculate all numerical answers to three significant figures.) What is the angle between F nad deltar?

Explanation / Answer

I am guessing this is the coffee cup question, since you asked it twice in here, so here is the answer

Apply umg = mv^2/r

u = v^2/rg

(.840) = v^2/(25)(9.8)

v = 14.3 m/s

If you go too fast, the cup will slide to the left
