The crate is placed on frictionless casters so that it slides down the ramp without friction. What is the final speed of the crate (in m/s) just as it reaches the bottom of the ramp? Use g = 9.81 m/s?.A penguin slides down an icy incline on his stomach, as shown in the diagram below. The coefficient of kinetic friction between the incline and the penguin's stomach is 0.15. The angle of the incline is 0 = 25 degrees. The total distance down the incline is 25 meters. The penguin gets a running start so his speed is 2.5 m/s when he begins to slide down the incline. What is the penguin's speed when he reaches the bottom of the incline? Hint: use Newton's 2nd law to calculate the acceleration of the penguin on the incline, then use kinematic equations to calculate the speed of the penguin when he reaches the bottom. 2.5 m/s 25 m 25°
