A 5.00-g bullet is fired horizontally into a 1.20-kg wooden block resting on a horizontal surface. The coefficient of kinetic friction between block and surface is 0.20. The bullet remains embedded in the block, which is observed to slide 0.230 m along the surface before stopping. What was the initial speed of the bullet?

acts on a 2.0 kg block placed on a frictionless horizontal surface . Initially the block is at rest at point A having coordinates (1.0 m, 3.0 m). If the force causes the block to be displaced from point A to point B having coordinates (4.0 m, 4.0 m) on an xy-coordinate system, find the block’s final speed. A) 3.0 m/s B) 5.0 m/s

If each eraser has a mass of 0.05 kg, each hits the wall with an initial speed of 3 m/s, and each one falls down to the bottom of the wall after hitting the wall, what is the average force that the wall exerts on the erasers? 2. A 15g bullet with a speed of 281 m/s hits a 3 kg block of wood and is lodged inside.
Jan 10, 2018 · Once we get the gear and flaps up we’ll pick the speed up to 280 mph and at 10,000 feet the FAA (Federal Aviation Administration) says I can go as fast as we want. We’re going to put the pedal to the metal; cruise on over to London doing approximately 500 mph. A student has to work the following problem: A block is being pulled along at constant speed on a ... A block is projected with speed v across a horizontal surface and slides to a stop due to friction. The same block is then projected with the same speed v up an incline where is slides to a stop due to friction. In

The expansion more than doubles Amazon Future Engineer’s reach, adding more than 3,000 new schools across the U.S. Nearly all Amazon Future Engineer schools serve a student body with a significant percentage of students from groups currently underrepresented in computer science and tech. Hundreds of schools are in rural areas, and more than ...
Update, 3/21: See this and this round-up of the news coverage and insightful commentaries. Update, 3/14: See W's response here. Another reader of the blog writes in about the " fair amount of research on the backlash women can face when they negotiate, what causes the backlash effects, and how to keep them to a minimum.

Block on a Ramp. A block starts from the bottom of a ramp of length 4 m and height 3 m with an initial velocity up the ramp of 4 m/s. The coefficients of friction for the block on the ramp are: μ s = 0.6 and μ k = 0.5.. The block slows as it slides up the ramp and eventually stops.
Two centuries ago, the first great railroad expansion drove our industrial revolution. Today, the U.S. is lagging behind Europe and China in rail safety and speed. Biden will develop a plan to ensure that America has the cleanest, safest, and fastest rail system in the world – for both passengers and freight.

A block of mass m, initially held at rest on a frictionless ramp a vertical distance H above the floor, slides down the ramp and onto a floor where friction causes it to stop a distance r from the bottom of the ramp. The coefficient of kinetic friction between the box and the floor is µk.

Example 4.13 A box is projected up a long ramp (incline angle with the horizontal = 37°) with an initial speed of 10 m/s. If the surface of the ramp is very smooth (essentially frictionless), how high up the ramp will the box go? What distance along the ramp will it slide? Solution. Areas of Science: Physics: Difficulty: Time Required: Very Short (≤ 1 day) Prerequisites: This project requires a basic understanding of algebra, trigonometry (sine and cosine functions), and physics (kinematics—two-dimensional projectile motion), or the willingness to learn about these subjects on your own.
