In the figures, the masses are hung from an elevator ceiling. assume the velocity of the elevator is constant. find the tensions in the ropes (in n) for each case. note that θ1 = 37.0°, θ2 = 53.0°, θ3 = 59.0°, m1 = 5.00 kg, and m2 = 9.00 kg. (due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in webassign.)

To travel at constant speed, a car engine provides 24kw of useful power. the driving force on the car is 600n. at what speed does it travel?

Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 2 s. what is your acceleration?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
