Mike Tyson's punch starts from rest and accelerates uniformly at 100 m/s² while moving 50 cm. The speed of his hand immediately before landing on his opponent's jaw is 50 m/s O2 m/s O 100 m/s O 10 m/s O 20 m/s.

Pen and Teller decided to do a magic trick involving a marble and a ball. Penn throws the marble straight upwards from the ground with an initial velocity of v⃗ 0, marble=10 m/s j^. At the exact moment that the marble was released, Teller throws the ball with an initial velocity of v⃗ 0, ball=5 [m/s] i^+10 [m/s] j^. Which of the following is true about the two objects? Select one: a. The ball will reach the ground first. b. Both objects will reach the ground at the same time. c. The marble will reach a greater height. d. The ball will reach the ground last.

Francesco, a pizza chef preparing the dough for your pizza is throwing it to expand it. In this process, you notice that a chunk of it comes off, flying separately from the rest and on to the floor. If Francesco is 6 feet and 0 inches tall, and the chunk flies off vertically straight up from this height at a speed of 1 m/s, with what speed does the chunk hit the ground?

The 25-Mg boxcar A 16m/s to the right is coasting on the horizontal track when it encounters a 9-Mg car B coasting at 2m/s toward it. If the two cars meet and couple together, determin common speed in m/s just after the coupling. Please see details below. Rounding numbers to 2 decimal places at the end.

At heights of 10 to 60 kilometers above the surface of the Earth, cosmic rays continually strike nuclei of oxygen and nitrogen atoms in the upper reaches of the atmosphere and produce muons (elementary particles of a mass about 207 times that of the electron). Some of the muons move vertically downward with a speed nearly that of light. Follow one of the muons on its way down. In a given sample of muons, half will decay to other elementary particles in 1.5 microseconds (1.5 × 10-6 seconds), as measured in a reference frame in which they are at rest. Half of the remainder decay in the next 1.5 microseconds, and so on. Analyze the results of this decay as observed in two different frames. Idealize the rather complicated details of the actual experiment to the following roughly equivalent situation: All muons are produced at the same height (45 kilometers); all muons have the same speed; all travel straight down; none are lost to collisions with air molecules on the way down. ●…

A man stands on the roof of a 15.0-m-tall building and throwsa rock with a speed of 30.0 m/s at an angle of 33.0 above the horizontal.Ignore air resistance. Calculate the speed of the rock just before it strikes the ground

Georgia, standing on the back of the pick-up truck, wants to throw her last piece of balut to her mortal enemy, Emma. before the truck started moving, the two women are separated by a distance of 2 m. For two seconds, the truck uniformly accelerated until it reached a velocity of 4 m/s which it then maintained. With hatred, Georgia throws the last piece of balut with a velocity of 12.5 m/s at an angle of 40° from horizontal, measured relative to the truck. If she makes the throw 2.8 seconds after the truck started moving, will she be able to hit Emma? Note that Emma is at rest due to exhaustion from their earlier fight and she cannot dodge the balut. Set your origin at point A. Neglect air resistance.

A small rocket is launched straight up. When at a height of 5.0km and velocity of 200.0m/s, it releases its booster and enters free fall. Neglecting air friction, what is the velocity of the rocket at a height of 6.0km on its way up? 143m/s 200m/s 244m/s 397m/s

My sable-colored Siberian husky, Samba, loves to run after huge objects (for instance, tree branches). I decide to chunk a 6 foot long stick for her to run after and bring back to me. I throw the stick at 1.45 ft/s in 2.14 s. In feet and to two decimal places, how far away did the stick land?
