Q2. A free-fall lifeboat is released from rest on an incline of 30º to the horizontal. The lifeboat takes 2.4 seconds to travel 10 m along the incline, at which point it starts to free-fall under the effect of gravity alone. Calculate EACH of the following:

(a) The acceleration of the lifeboat as it travels down the incline;

(b) The velocity at which the lifeboat leaves the incline;

(c) The horizontal distance the lifeboat will travel after leaving the incline when the vertical distance to the water at this point is 40 m;

(d) The velocity and angle at which the lifeboat enters the water.
