Question 25 (1 points) (884179) (Friction, Internal Work and Heat} A block of mass 333 kg starts at rest at the top of a frictionless ramp that makes an angle of 9 : 44.1O below the horizontal After it slides without friction down the entire 2.98 m length of the ramp, it begins to slide horizontally along a rough, horizontal concrete surface with a coefcient of kinetic friction of M = 0348 until it slows to a complete stops How far does the block slide horizontally along the concrete before it stops? [Note : this question may contain more information than is necessary to solve the problem. Assume that no energy is lost to deformation or sound at the transition between the ramp and the concrete] Image size: 5 M L Max Question 26 (1 points) (833459) {Friction, Internal Work and Heat} A motor is powered by a battery with an energy capacity of Ebattery =1 WHr (1 WHr = 3600 Joules). The motor sits at the top of a concrete ramp and is connected to a cable that is used to pull a 74.6-kg wood crate up the concrete ramp with a coefficient of kinetic friction of 0.315 and an angle of 21.9 . above the horizontal. Assume that the net energy efficiency of the battery-powered motor is only & = 0.25 for this application. (this is the fraction of the energy capacity that can be converted into useful mechanical work; the rest is lost as heat in the motor or battery). The wood crate is initially stationary at the bottom of the ramp. How far along the ramp can the motor pull the crate before the battery is completed drained? (Assume the battery is initially charged to full capacity). Please enter a numerical answer below. Accepted formats are numbers or "e" based scientific notation e.g. 0.23, -2, 1e6, 5.23e-8
