A 55-kg diver stands at the end of a diving board located 10 m above the water level. The diving board is held down at one end by an anchor bolt. The fulcrum is located at 1.4 m from the bolt and the total length of the board is 3.9 m.
- Draw a free body diagram showing the forces acting on the diver.
- Calculate the torque that she exerts on the board with respect to the fulcrum. Neglect the mass of the board.
- Calculate the forces that the bolt and the fulcrum exert on the board?
The diver springs upwards to a height of 1.2 m above the board and dives into water. Ignoring air resistance:
- Find her initial vertical velocity at the instant of jumping.
- Find her speed when she enters the water. This time assume the diver’s trajectory to be projectile. (Hint: use work-energy theorem)

1) A diver of mass 43.0kg stands on the end of a uniform diving
board over the water. The board is 7.00m long and has a mass of
75kg. The end of the board opposite the diver is attached to the
platform. The bounce of the board is adjusted by a roller
underneath that can be moved back and forth. The roller is 2.80 m
from the fixed end of the board. a) What are the magnitude and the
direction...

A diver springs upward from a board that is 2.70 m above the
water. At the instant she contacts the water her speed is 11.7 m/s
and her body makes an angle of 64.4 ° with respect to the
horizontal surface of the water. Determine her initial velocity,
both (a) magnitude and (b) direction.

A boy stands on a diving board and tosses a stone into a
swimming pool. The stone is thrown from a height of 2.50 m above
the water surface with a velocity of 4.00 m/s at an angle of 60.0°
above the horizontal. As the stone strikes the water surface, it
immediately slows down to exactly half the speed it had when it
struck the water and maintains that speed while in the water. After
the stone enters the water,...

4. A boy stands on a diving board and tosses a stone into a
swimming pool. The stone is thrown from a height of 2.8 m above the
water surface with a velocity of 5.6 m/s at 72 degrees above the
horizontal.
a) First determine the time it is airborne. (I got 1.48 sec)
b) Now find its impact velocity. (Vx=2 m/s and Vy=9.17 m/s)
As the stone impacts the water, it instantly slows down to half
its previous velocity,...
