calculate the tangential acceleration( experts plz help)

None

A hot air ballon raises fro ground at a constant rate of 2m/s in y direction.As it ascends it acquires a velocity in x direction (due to wind) Vx =5Y where Y is the ascent.Calculate

tangential acceleration

and compute Y as a function of x...........

you havent mentioned what V is and what x is. the equation Vx=5Y is dimensionally incorrect

Vx is velocity in x direction

Vx =5Y = 5 x 2t (as vertical velocity is 2 m/s and ascent Y = 2 x t, where t is time elapsed after ascent has started)

Hence Vx = 10t

Tangential acceleration = Acceleration perpendicular to direction of gravity (gravitational acceleration is normal or perpendicular to earth's surface) = Acceleration along the direction of Vx =

= d(Vx)/dt = 10 m/s2
