Asquare block with mass m = 100g and side length s = 3.0cm resting on a flat surface at height h = 15cm at an angle θ = 30omeasured from the x-axis is struck by a spring driven plunger with spring constant k1 = 10. the coefficients of friction between the block and all surfaces are µs = .2 & µk = .1 the initial velocity of the block after being struck is v0 = 1.25 m s 2.2 problems 2.2.1 where does the block come to rest? assume: a) the second spring is level with the ground and exerts exactly enough force to change the y-component of the block’s velocity b) the block lands on the very edge of the second raised area at the top of its motion after reboundin

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
