A:
A projectile of mass 2.0 kg is fired in the air at an angle of 40.0 ° to the horizon at a speed of 50.0 m/s. At the highest point in its flight, the projectile breaks into three parts of mass 1.0 kg, 0.7 kg, and 0.3 kg. The 1.0-kg part falls straight down after breakup with an initial speed of 10.0 m/s, the 0.7-kg part moves in the original forward direction, and the 0.3-kg part goes straight up. a. Find the speeds of the 0.3-kg and 0.7-kg pieces immediately after the break-up.
b. How high from the break-up point does the 0.3-kg piece go before coming to rest?
c. Where does the 0.7-kg piece land relative to where it was fired from?

- An object, in initially travelling 45° south of east at 100 m/s, explodes into three separate pieces. A 2.0 kg fragment travels due south at 105 m/s, while a 4.0 kg fragment travels due east at 155 m/s. The last fragment has a mass of 3.0 kg. The third fragment travels at an unknown velocity. Calculate its direction and magnitude of this unknown velocity.A little fish has mass 0.400 kg and is floating motionlessly in the water, minding its own business, when a big fish (mass 2.00 kg) comes along and swallows it whole. If the big fish was gliding along at a constant velocity of 1.25 m/s before it swallowed the little fish, what will its velocity be immediately after the "collision"? O 1.04 m/s 7.50 m/s 1.50 m/s 0.250 m/sA 46.7-kg person, initially at rest, throws a 0.143-kg snowball forward with a horizontal speed of 33.5 m/s. A second person, with a mass of 47.5 kg, catches the snowball. Both people are on skates. The first person is initially at rest, as mentioned, and the second person is initially moving with a speed of 1.45 m/s toward the first person. Disregard air resistance and the friction between the skates and the ice. Take the direction in which the snowball is thrown to be the positive direction. Indicate the directions of the final velocities with the signs of your answers. To receive full marks, you must include a diagram showing the physical situation. (a) Calculate the velocity of the first person immediately after they throw the snowball. (b) Calculate the velocity of the second person immediately after they catch the snowball.

- A 4900 kg open train car is rolling on frictionless rails at 18.6 m/s when it starts pouring rain. A few minutes later the car's speed is 15.4 m/s. What mass of water (in kg) has collected in the car?A block of mass 1.43 kg is placed on a frictionless floor and initially pushed northward, whereupon it begins sliding with a constant speed of 5.70 m/s. It eventually collides with a second, stationary block, of mass 3.39 kg, head-on, and rebounds back to the south. The collision is 100% elastic. What will be the speeds of the 1.43-kg and 3.39-kg blocks, respectively, after this collision?Jack (mass 52.0 kg) is sliding due east with speed 8.00 m/s on the surface of a frozen pond. He collides with Jill (mass 48.0 kg), who is initially at rest. After the collision, Jack is traveling at 5.00 m/s in a direction 34.0° north of east. Ignore friction.
- Two carts undergo a perfect inelastic collision. The mass of the first cart, m1 = 4.639 kg, and the carts initial velocities (before collision) are v1 = 6.943 m/s and v2 = - 2.871 m/s. If the final velocity of the two-cart (after collision) is 5.355 m/s, the mass of the second cart m2 (kg) is:: 2 8: F2 10. A small ball of mass m₁ = 0.280 kg is moving at a speed of 3.55 m/s. It strikes a stationary larger ball of mass m₂ = 0.580 kg. After the collision, the balls follow the path shown in the figure, where a = 25.0° and 3 = 53.0°. What is the magnitude of the velocity of the smaller ball after the collision?

It seems like a good idea for him to jump over the rail and let the skateboard pass under the rail. The mass of the boy is 38.8 kg, the mass of the skateboard is 2.43 kg, the initial cruising speed is +5.22 m/s, and the instant after leaving contact with the board, the boy's velocity relative to the sidewalk is 5.33 m/s, 9.27° above the horizontal. If we ignore the force of friction between the skateboard and the sidewalk, determine the skateboard's velocity relative to the sidewalk at the instant the boy leaves the board. m/s
- A block of mass 1.98 kg is placed on a frictionless floor and initially pushed northward, whereupon it begins sliding with a constant speed of 5.64 m/s. It eventually collides with a second, stationary block, of mass 3.83 kg, head-on, and rebounds back to the south. The collision is 100% elastic. What will be the speeds of the 1.98-kg and 3.83-kg blocks, respectively, after this collision? 1.26 m/s and 2.31 m/s 1.80 m/s and 3.84 m/s 3.84 m/s and 1.80 m/s 2.61 m/s and 2.82 m/sTwo metal blocks are sliding across a frictionless floor. Block one has a mass of 4.75 kg and is sliding with a velocity of 3.25 m/s east (take east to be the positive x-direction). Block two has a mass of 7.25 kg and is sliding with a velocity of 7.39 m/s north (take north to be the positive y-direction). They collide and bounce apart but it is NOT a perfectly elastic collision. After the collision, block one is moving at 4.50 m/s at 75.0º north of east. Determine block two’s velocity in the Y-DIRECTION after the collision. (Report your answer in units of m/s, but only type the numerical answer (and any applicable sign).)
