? An object with total mass mtotal = 15 kg is sitting at rest when it explodes into three pieces. One piece with mass m1 = 4.8 kg moves up and to the left at an angle of 0, = 24° above the -x axis with a speed of v, = 28.3 m/s. A second piece with mass m, = 5.2 kg moves down and to the right an angle of 02 = 29° to the right of the -y axis at a speed of v2 = 21.5 m/s.
What is the velocity (in m/s) of a 905 kg car initially moving at 25.0 m/s, just after it hits a 135 kg deer initially running at 12.5 m/s in the same direction? Assume the deer remains on the car. (Enter the magnitude.)
Two figure skaters, one weighing 625 N and the other 725 N, push off against each other on very smooth ice. a)If the heavier skater travels at 1.50 m/s, how fast will the lighter one travel? b)How much kinetic energy is "created" during the skaters' maneuver?
I;m not sure how to fix this answer, it will not allow 10^3.
A railroad car of mass 2.56 x 104 kg is moving with a speed of 4.10 m/s. It collides and couples with three other coupled railroad cars, each of the same mass as the single car and moving in the same direction with an initial speed of 2.05 m/s. (a) What is the speed of the four cars after the collision? (Round your answer to at least two decimal places.) m/s (b) How much mechanical energy is lost in the collision?
Billiard bollz. Three billiard balls are aligned horizontally as shown. Efren Bata Reyes hits ball 1 making it travel at v = 6.00 [m/s] to the right. Ball 1 then collides with a stationary ball 2. Then, ball 2 collides with ball 3 that was travelling at v = 4.50 [m/s] to the left. The masses of ball 1, 2, and 3 are 3.50 [kg], 2.50 [kg], and 1.50 [kg] respectively. Assuming all collisions are elastic, what is the magnitude of the final velocity of ball 3? vi V3 2 3 O 7.00 [m/s] O 9.88 [m/s] O 1.62 [m/s] O 7.63 [m/s]
One hazard of space travel is debris left by previous missions. There are several thousand objects orbiting Earth that are large enough to be detected by radar, but there are far greater numbers of very small objects, such as flakes of paint. Calculate the force exerted by a 0.100 mg chip of paint that strikes a spacecraft window at a relative speed of 4.00 × 10³ m/s, given the collision lasts 6.00 x 10-8 s.
An outlaw cuts loose a wagon with two boxes of gold, of total mass 300 kg, when the wagon is at rest 50 m up a 6.0° slope. The outlaw plans to have the wagon roll down the slope and across the level ground, and then fall into a canyon where his accomplices wait. But in a tree 40 m from the canyon’s cliff wait the Lone Ranger (mass 75.0 kg) and Tonto (mass 60.0 kg). They drop vertically into the wagon as it passes beneath them (Fig.). (a) If they require 5.0 s to grab the gold and jump out, will they make it before the wagon goes over the cliff? The wagon rolls with negligible friction. (b) When the two heroes drop into the wagon, is the kinetic energy of the system of heroes plus wagon conserved? If not, does it increase or decrease, and by how much?
A space station initially at rest, consists of a 1000-kg sphere and a 4000-kg sphere joined by a light cylinder, as seen in the figure below. A thruster rocket which can be located either on the lighter or heavier sphere, is fired brietly to provide a 1000 N force for 5s, in two different scenarios. Assume the 1000 kg sphere is located 40 m from the CM of the ship, and the 4000 kg mass is at 10 m from the CM. a) Compute the ratio of the angular accelerations a's during the firing of the rockets, for the two different scenarios.
