Q1. A box slides down a 38° ramp with an acceleration of 1.95 m/s2. Determine the coefficient of kinetic friction between box and ramp.
Q2. The perspective provided by Multiple-Concept is useful here. The highest barrier that a projectile can clear is 15.60 m, while the projectile is launched at an angle of 23.0 ° above the horizontal. What is the projectile's launch speed?
