Pls help me answer 1-5 i need it in 20 mins pls thanks about power in physics 1. An 102 kg hiker climbs Mt. Humphrey near Flagstaff. During a 2 hour period, the hiker's vertical elevation increases by 530 meters. Find the power generated to increase the hiker's PEg. 2.)A 2014 Ford Mustang GT is driving down a road with a constant speed of 34 m/s. The engine must exert a 11,296 N force to maintain this speed. What is the power rating of the engine? Hint: Use the definition of speed to help you solve! 3.Bulky counters with his claim of lifting a 249 kg box 18 meters vertically, in 20 seconds. What is Bulky's power? 4.)How many joules does your 2,474 W blow drier transfer if you dry your hair in 8 minutes? 5.)The trains on the Viper are raised from 13 m above ground at the loading platform to a height of 69 m at the top of the first hill in 57 s. Assume that the train (including passengers) has a mass of 2,773 kg. Ignoring frictional losses, what power motor would be required to accomplish this task
