(a) A canoeist (person) of mass mp sits at rest at the back end of a canoe. The canoe has a length L, a mass me, and is initially at rest in the still water of a lake with its front end a distance d; from the dock. Then the canoeist realizes that the paddle is still on the dock, and carefully moves to the front of the canoe. After the person reaches the canoe's front end, what will the distance df of the canoe's front end be from the dock? (b) Evaluate your result for mp: = 72 kg, mc = 21 kg, L= 4.2 m, and di = 0.2 m. Will the dock be within reach from the front of the boat? Check: For mp = 56 kg, mc = 23 kg, L = 3.8 m and di = 0.50 m you should find df = 3.2 m.

A bullet, having a mass of 0.04 kg moving with a velocity of 450 m/s penetrates a distance of 0.08 m into a wooden block firmly attached to the earth. Assuming a constant accelerating force, compute the following: a) the acceleration of the bullet, b) the accelerating force, c) the time of acceleration, and d) the impulse of the collision.
In an experiment designed to determine the velocity of a bullet fired by a certain gun, a wooden block of mass M = 505.0 g is supported only by its edges, and a bullet of mass m = 6.00 g is fired vertically upward into the block from close range below. After the bullet embeds itself in the block, the block and the bullet are measured to rise to a maximum height of 35.0 cm above the block's original position. What is the speed of the bullet just before impact? m/s
In an experiment designed to determine the velocity of a bullet fired by a certain gun, a wooden block of mass M = 560.0 g is supported only by its edges, and a bullet of mass m = 7.75 g is fired vertically upward into the block from close range below. After the bullet embeds itself in the block, the block and the bullet are measured to rise to a maximum height of 42.5 cm above the block's original position. What is the speed of the bullet just before impact?
Ricardo, of mass 80 kg, and Carmelita, who is lighter, are enjoying Lake Merced at dusk in a 30 kg canoe.When the canoe is at rest in the placid water, they exchange seats, which are 3.0 m apart and symmetrically located with respect to the canoe’s center. If the canoe moves 40 cm horizontally relative to a pier post, what is Carmelita’s mass?
Ron, of mass 80 kg, and Harry, who is lighter, are enjoying the Great Lake at dusk in a 30 kg canoe. When the canoe is at rest in the still water, they exchange seats, which are 3 m apart and symmetrically located with respect to the canoe’s center. If the canoe moves 40 cm horizontally relative to a pier post, what is Harry’s mass?

A car with mass mc = 1153 kg is traveling west through an intersection at a magnitude of velocity of vc = 11 m/s when a truck of mass mt = 1998 kg traveling south at vt = 11 m/s fails to yield and collides with the car. The vehicles become stuck together and slide on the asphalt, which has a coefficient of friction of μk = 0.5. (a) Write an expression for the velocity of the system after the collision, in terms of the variables given in the problem statement and the unit vectors i and j. (b) How far, in meters, will the vehicles slide after the collision?
An amateur skater of mass M is trapped in themiddle of an ice rink and is unable to return to the sidewhere there is no ice. Every motion she makes causes her toslip on the ice and remain in the same spot. She decides totry to return to safety by removing her gloves of mass m andthrowing them in the direction opposite the safe side. (a) Shethrows the gloves as hard as she can, and they leave her handwith a velocity vgloves. Explain whether or not she moves. Ifshe does move, calculate her velocity vgirl relative to the Earthafter she throws the gloves. (b) Discuss her motion from thepoint of view of the forces acting on her.
