Grey decides to take his jet ski out for a spin. He first skis 6 meters south and then turns west and skis 8 meters. What is Grey's distance from the dock? What is the displacement from the dock? Make sure to show all your work and provide proper units and direction. Finally, determine which measurement is a vector quantity and which is a scalar quantity

A17,250 kg rocket is pushed with a thrust of 6,450,284 n. what is the acceleration of the rocket?

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
