3 To Load The Sleigh Santa Starts The Present Loading Machine Presents Slide Down A 30 Degree Ramp Coefficient Of Kin 1 (113 KiB) Viewed 23 times

3. To load the sleigh, Santa starts the present loading machine. Presents slide down a 30 degree ramp coefficient of kinetic friction of 0.25. What is the acceleration of the present as it moves down the ramp? 30° If the ramp is two meters long, how fast are the presents moving when they hit the bottom? 4. A 10 gram block sits at rest on a horizontal surface as shown. It is connected by a string to a 50 gram block which hangs vertically. The coefficient of friction between the block and the surface is 0.4. What is the acceleration of the 50 gram block? What is the tension in the string? 5) Coby decides that the solution to the zombie problem is napalm(he dissolves all the leftover amazon packing Styrofoam in acetone and mixes it with gasoline). He can spray napalm(c = 2200J/kg) at 1080°C onto zombies. If a zombie (c = 4190J/kg) weighs 62kg, how much napalm must he spray to cause all of it to be destroyed? (Fat sustains combustion at 242°C) b) Coby is using a repurposed garden sprayer to spray the napalm with another helpful student holding a lighter for ignition (DDTAH!) If the 500g sprayer handle had a 30 cm stroke(h = 30cm), and the sprayer ejects 50g of napalm per pump, how fast is the napalm traveling when it leaves the sprayer? Weber c) If Coby holds the sprayer 1.6 meter off the floor, what is the maximum range of the napalm spray? d) If the zomble is advancing at .3 m/s and Coby can pump the sprayer 2x/second, can he destroy the zombie? If not, what will be the temperature of the zombie when it reaches him?
