A man is sitting on the shore of a river. He is in the line of a 1.0m long boat and is 5.5m away from the centre of the boat. He wishes to throw an apple into the boat. If he can throw an apple into the boat. He wishes to throw an apple into the boat. If he can throw the apple only with a speed of 10m/s, find the minimum and maximum angles of projection for suceeful shot. Assume that the point of projection and the edge of the boat are in the same horizontal level

Answer:
As shown in figure, when apple is thrown from A to B, range is 4.5 m. Similarly, when apple is thrown from A to C, range is 6.5 m.
Range of projectile R = ( u2sin2α ) / g , where u is projection velocity and α is angle of projection.
Angle of projection α for given range R is given by, α = 
required angle of projection to throw apple from A to B is given by, 
required angle of projection to throw apple from A to C is given by,
