Question
1) A 60kgg scuba diver with a volume of 0.83m^3 is submerged in seawater at a depth of 50 meters. What is the pressure (N/m^2) felt by the scuba diver alone?
2) An airplane is accelerating at a constant rate of 3.1 m/s^2 toward the eaast (to the right). The plane passes the terminal with an initial velocity of 70 m/s and accelerates for 9.7 more seconds before taking off. What is the velocity of the plane at the end of this 9.7 seconds (at takeoff)? How far has it traveled this 9.7 second interval?
INITIAL VELOCITY_____________M/S
ACCELERATION_______________M/S^2
ELAPSED TIME__________________SEC
FINAL POSITION____________M
FINAL VELOCITY_______________M/S
Explanation / Answer
1) The pressure felt by scuba diver = density of water*g*depth = 1000*9.8*50 = 490000 N/m2
2) v=u+at = 70+(3.1*9.7) = 100.07 m/s
s=ut+(1/2)at2
= (70*9.7)+(1/2)*(3.1)*(9.72)=824.84 m
