A group of highway engineers has designed a curved section of a road. The speed limit on this road is 30.0 m/s (roughly 60 mph). The radius of the curve is designed so that the road is barely safe to drive on if µ = 1.00. If it rains or freezes and µ drops to 0.500, then what would be the maximum safe speed in those conditions?

Aman tries to push a box of mass 4 kg with a force of 5 n but the box remains stationary if the coefficient of static friction is 0.45, what is the value of the maximum force of friction?

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.
