Chapter 8, Problem 8.28E
You are standing on a large sheet of frictionless ice and holding a large rock. In order to get off the ice, you throw the rock so it has velocity 12.0 m/s relative to the earth at an angle of 35.0° above the horizontal. If your mass is 70.0 kg and the rock’s mass is 3.00 kg, what is your speed after you throw the rock? (See Discussion Question Q8.7.)

- A rocket has total mass Mi = 360 kg, including Mfuel = 330 kg of fuel and oxidizer. In interstellar space, it starts from rest at the position x = 0, turns on its engine at time t = 0, and puts out exhaust with relative speed ve = 1 500 m/s at the constant rate k = 2.50 kg/s. The fuel will last for a burn time of Tb = Mfuel/k = 330 kg/(2.5 kg/s) = 132 s. (a) Show that during the burn the velocity of the rocket as a function of time is given by v(t)=veln(1ktMi) (b) Make a graph of the velocity of the rocket as a function of time for times running from 0 to 132 s.

In the middle of the lake is a 1,000 kg boulder. When the sled crashes into the boulder, he is propelled over the boulder and continues sliding over the ice at 11.7 m/s. If the boy's mass is 40.0 kg and the sled's mass is 20.0 kg, what are the speeds (in m/s) of the sled and the boulder after the elastic collision? (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.) sled m/s boulder m/sarrow_forwardA loaded gun is dropped on a frozen lake. The gun fires, with the bullet going horizontally in one direction and the gun sliding on the ice in the other direction. The bullet's mass is 0.04 kg, and its speed is 320 m/s.

- A 730 N student stands in the middle of a frozen pond having a radius 5.0 m. She is unable to get to the other side due to a lack of friction between her shoes and the ice. To overcome this difficulty, she throws her 2.6 kg physics textbook horizontally toward the north shore at a speed of 5.0 m/s. How long does it take her to reach the south shore?arrow_forwardKaya, a crew member on an interplanetary space ship, is on a spacewalk. She realizes that her ship is moving away from her at 0.5 m/s. She and her spacesuit have a total mass of 95 kg. Her space suit includes a 15 kg backpack, which is included in the 95 kg total mass.a). What is the minimum velocity she will have to throw the backpack so that she can gain enough velocity to eventually catch up with the ship? b). Kaya applies an average force of 400 N to the backpack for 0.05 seconds. Will Kaya make it back to the ship? If so, determine how much time it will take for her to reach the ship. If not, determine how much more force she would need to apply to make it back.arrow_forwardYou and another astronaut are in space. You throw a tool to them that has a mass of 17kg.

- The mass of a particular eagle is twice that of a hunted pigeon. Suppose the pigeon is flying north at vi2=16.9m/s when the eagle swoops down, grabs the pigeon, and flies off. At the instant right before the attack, the eagle is flying toward the pigeon at an angle ?=48.7° below the horizontal and a speed of vi1 =37.7m/s. What is the speed of the eagle immediately after it catches its prey? What is the magnitude of the angle, measured from horizontal, at which the eagle is flying immediately after the strike?arrow_forwardA cat of 20 kg mass is running at 8.0 m/s toward a stationary skateboard with a mass of 2 kg. The cat jumps on the skateboard once it reaches it. The skateboard and cat roll forward together without friction until they reach a ramp 30◦ above horizontal. If the coefficient of kinetic friction between the skateboard and the ramp is µk =0.3, what is the maximum height the skateboard can reach?arrow_forwardThe carbon isotope 14C is used for carbon dating of archeological artifacts. 14C (mass 2.34 x 10-26 kg) decays by the process known as beta decay in which the nucleus emits an electron (the beta particle) and a subatomic particle called a neutrino. In one such decay, the electron and the neutrino are emitted at right angles to each other. The electron (mass 9.11 x 10-31 kg) has a speed of 5.00 x 107 m/s and the neutrino has a momentum of 8.00 x 10-24 kg • m/s. What is the recoil speed of the nucleus?arrow_forward
