A 47.0 kg woman stands up in a 70.0 kg canoe of length 5.00 m . She walks from a point 1.00m from one end to a point 1.00m from the other end.
Part A) If the resistance of the water is negligible, how far does the canoe move during this process? (answer in meters)
Find out the velocity with which he strikes the water. (Hint: When the diver reaches the water, his displacement is y = -3 m (measured from the board), assuming that the downward direction is chosen as the negative direction.)
A flywheel with a radius of 0.310m starts from rest and accelerates with a constant angular acceleration of 0.660rad/s2, Compute the magnitude of the tangential acceleration, the radial acceleration
A 61.0kg skater moving initially at 3.78m/s on rough horizontal ice comes to rest uniformly in 3.24s due to friction from the ice
The velocity component of the particle at x = 8.0 m is 2.8 m/s. Illustrate what is the acceleration component during this time interval?
What is the frictional force
A projectile with mass .065 kg is fired at and embeds itself in a pendulum with mass .19 kg. What is the percent kinetic energy loss during the perfectly inelastic collision
If the atom could be enlarged to the size of a football field, and the electrons were represented by gnats, how large would the nucleus be
A woman on a bridge 71.0 m high sees a raft floating at a constant speed on the river below. She drops a stone from rest in an attempt to hit the raft. The stone is released when the raft has 6.60 m more to travel before passing under the bridge. ..

How much higher would the ball have gone in a vacuum. The time constant of an RC circuit is 4.8 s. How much time t is needed for the capacitor (uncharged initially) to gain one-half of its full equilibrium charge.
A person is riding a bicycle, and its wheels have an angular velocity of 26.9 rad/s. Then, the brakes are applied and the bike is brought to a uniform stop. What is the anguar acceleration (in rad/s2) of each wheel
