In a boat in the lake, someone on the shore used a rope to pull the boat through the pulley H above the water. If the rope is taken in at the speed V0, calculate the speed and acceleration of the ship when it reaches the shore X.
Tip:
tanθ=h/x
cosθ=vo/v
Higher than two at the same time to obtain v
x^2+h^2=lo^2
x'^2+h^2=(lo-vot)^2
Solve the available function x'(t) simultaneously, and then find the second derivative of the available acceleration.
