After the 2,500-m swim, Charlie [mass mCh = 42 kg] wants to impress Colby [mC = 34 kg] and jumps off the 10-m platform. Charlie jumps upwards and reaches the maximum height of 2.5-m above the platform before turning around and falling towards the water. We only consider the motion along the vertical.
a) Find the velocity [vector] of Charlie as he jumps off the spring board
b) Find the velocity [vector!] of Charlie as he hits the water surface.
c) How long is Charlie airborne?
d) Charlie then plunges into the water and reaches the maximum depth 4.6-m [15 ft] below the surface. What is the (average) magnitude of the deceleration of Charlie while he is submerged in water.
e) What is the (average) force that the water exerts on Charlie as he is submerged in the water?

Two friends Colby [mass mC = 34 kg] and Charlie [mass mCh = 42
kg] are avid swimmers. Colby is a master swimmer, while Charlie
only swims recreationally. They both start on one side of pool (x =
0) at the same time (t = 0). The pool is separated into lanes along
the “long course” so that the other end is at x = 50 m. Colby swims
2,500 m in 55 minutes; we assume that Colby and Charlie...

A gymnast with mass m1 = 42 kg is on a balance beam
that sits on (but is not attached to) two supports. The beam has a
mass m2 = 112 kg and length L = 5 m. Each support is 1/3
of the way from each end. Initially the gymnast stands at the left
end of the beam.
1)
What is the force the left support exerts on the beam?
N
2)
What is the force the right support...

A child of mass mc = 35 kg stands on the rim of a
frictionless merry go round, which acts like a solid disk of mass
mm = 55 kg and radius r = 1.1 m. With the merry go round
at rest, they throw a rock of mass mr = 1.0 kg with a
velocity v = 18 m/s relative to the ground in a direction
horizontal to the ground, and tangent to the rim of the merry go...

A
girl and her bicycle have a total mass of 42 kg. At the top of the
hill her speed is 4.00 m/s. The hill is 14.3 m high and 112 m long.
If the force of friction as she rides down the hill is 20N. what is
her speed at the bottom?

Calculate the gravity
Mass of Andromeda galaxy
1.5 × 10^42 kg
Mass of Milky Way galaxy
8.0 × 10^1 % of Andromeda's mass
Distance between the galaxies
2.9 *10^6 light years
1) Even though it is not quite right for this situation, use
Newton's Law of Gravitation to calculate the force of gravity (in
Newtons) between the Milky Way galaxy and the Andromeda galaxy
today.
2) In the future, will the force of gravity between the two
galaxies increase, decrease or stay...
