Question

A diver springs upward from a board that is 3.01 meters above the water. At the instant she contacts the water her speed is 9.37 m/s and her body makes an angle of 76.3° with respect to the horizontal surface of the water. Determine her initial velocity.

Answer #1

A diver springs upward from a board that is 2.84 meters above
the water. At the instant she contacts the water her speed is 8.67
m/s and her body makes an angle of 73.9° with respect to the
horizontal surface of the water. Determine her initial
velocity.

A diver springs upward from a board that is 3.20 meters above
the water. At the instant she contacts the water her speed is 8.75
m/s and her body makes an angle of 79.4° with respect to the
horizontal surface of the water. Determine her initial
velocity.

A diver springs upward from a board that is 3.03 meters above
the water. At the instant she contacts the water her speed is 8.98
m/s and her body makes an angle of 73.7° with respect to the
horizontal surface of the water. Determine her initial
velocity.
Please explain how to use cos and sin.

a
diver springs upward from a board that is 2.92 meters above water .
At the instant she contacts the water her speedis 9.48m/s and her
body makes an angle of 73.6 deg with respect to the horizontal
surface of the water .(note at the instant she contacts the water
she is traveling in the same directionas her body is pointed.)
Determine her intial speed as she leaves the board.

A diver springs upward from a board that is 2.90 m above the
water. At the instant she contacts the water her speed is 11.0 m/s
and her body makes an angle of 62.7 ° with respect to the
horizontal surface of the water. Determine her initial velocity,
both (a) magnitude and (b) direction.

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...

Q2. 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.
(a) Draw a free body diagram showing the forces acting
on the diver.
(b) Calculate the torque that she exerts on the board
with respect to the fulcrum....

A diver of mass 50-kg jumps from a cliff at 5.00m/s upward at an
angle of 30o as measured from the horizontal surface of the cliff.
The cliff is 20 m above the surface of a body of water. (Friction
is negligible)
Determine
a) the final velocity of the diver just before the diver strikes
the body of water using Projectile Motion Kinematics
b) the magnitude of the final velocity of the diver just before
the diver strikes the body...

A diver leaves the end of a 4.0 m high diving board and strikes
the water 1.3 s later, 3.0 m beyond the end of the board. Ignoring
the height of the diver (assume she is a particle), determine: a)
her initial velocity and angle at which she jumped, b) her maximum
height reached, and c) the velocity and angle with which she enters
the water.
