A spaceship with a mass of 4.50  104 kg is traveling at 5.89  103 m/s relative to a space station. What mass will the ship have after it fires its engines in order to reach a speed of 7.86  103 m/s? Assume an exhaust velocity of 4.36  103 m/s. kg

A spaceship of mass M is traveling in deep space with velocity=D40 km/s relative to the Sun. It ejects a rear stage of mass 0.1 M with a relative speed u = ?10km/s. What then is the velocity of the spaceship

A 17 kg penguin waddling west at a velocity of 7.8 m/s collides with a stationary 12 kg penguin. After the collision, the 17 kg penguin is traveling at a velocity of 4.3 m/s at 20 degrees S of W. What is the 12 kg penguin's speed after the collision?

A spaceship of mass 2.30x10 kg is cruising at a speed of 4.60x105 m/s when the antimatter reactor fails, blowing the ship into three pieces. One section, having a mass of 5.20x105 kg, is blown straight backward with a speed of 2.50x106 m/s. A second piece, with mass 7.70x105 kg, continues forward at 1.00x106 m/s.

There is a large crater in Arizona called Meteor Crater. It is estimated that it was formed about 20,000 years ago by a meteorite that had a mass of about 5 x 10^10 kg and was traveling at a speed of 7.5 km/sec. How fast could this meteorite have hit the Earth (whose mass is 6 x 10^24 kg) if we assume a head-on collision?

One day a responsible young college student is driving his blue car (m = 931 kg) in an easterly direction and obeying the traffic laws with a leisurely velocity of v, = 12.12 m/s. Out of nowhere comes a crazed soccer mom driving her red minivan (M = 1261 kg) in a northerly direction at the insane velocity of V, = 21.81 m/s crashing straight into the innocent student. Their vehicles intertwine into a tangled pile of wreckage that eventually slides to a stop. We'll take the coefficient of friction to be: µk = 0.623. d%3? V2(wreckage) V2y=? v,(car) V=? V,(van) Not to scale The following summarizes the sequence of events occur: 1→ 2: The cars suffer an inelastic collision. • 2 → 3: The cars slide to a stop. Determine all the following: The x-component of the velocity of the wreckage immediately after the collision: V2x The y-component of the velocity of the wreckage immediately after the collision: V2y m/s The magnitude of the velocity of the wreckage immediately after the collision: V2 =…

An astronaut comes loose while outside the spacecraft and finds himself floating away from the spacecraft with only a big bag of tools. In desperation, the astronaut throws his bag of tools in the direction of his motion (away from the space station). The astronaut has a mass of 102 kg and the bag of tools has a mass of 10.0 kg. If the astronaut is moving away from the space station at 1.80 m/s initially, what is the minimum final speed of the bag of tools (with respect to the space station) that will keep the astronaut from drifting away forever? minimum final speed: m/s

A robber with a mass of 61.91 kg runs away from his victim at a velocity of 7.911 m/s. A 119.1 kg cop running at 5.032 m/s from the opposite direction collides with and tackles the thief. As the cop is taking down the thief, what is their horizontal velocity?

A saturn 5 rocket must travel 17, 800 mph to escape the gravitational pull of the earth and enter space. The rocket weight 6.2 million pounds, and the initial specific impulse lasts 263 seconds. What impulse is required for the rocket to meet the 17, 800 mph momentum in needs, using the formula FT=MV?
