Free webinar on Robotics (Block Chain) Learn to create a Robotic Device Using Arduino
30th Jan @ 5:00PM for Grade 1 to 10
A balloon is rising vertically above a level, a straight road a constant rate 1 m/s. Just when the balloon is 65m above the ground, a bicycle moving at a constant rate of 17 m/s passes under it. How fast is the distance b/w the bicycle and balloon increasing 3 seconds later? A)11 m/s B) 9 m/s C) 13 m/s D) 15 m/s A balloon is rising vertically above a level, a straight road a constant rate 1 m/s.

we do this by coordinate geometry baloon (0,65+1*t)bicycle (17t,0)z^2=289*t^2+(65+t)^22zdz/dt=289*2*t+2(65+t)we can dz/dt=11
