Anovice golfer on the green takes three strokes to sink the ball. the successive displacements of the ball are: - 4.0 m north - 2.0 m northeast - 1.0 m at 30◦ to the west of south starting at the same initial point, an expert golfer could make the hole in what single displacement?

its displacement is given in vector form as follows

now the total displacement due to all three is given as

so magnitude of displacement is

direction is given as

so the ball will be displaced by 4.63 m at angle 78.7 degree North of East

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

the answer to this is proletariats.

hope this : )
