# Bullet of mass embeds itself in awooden block with mass which then compresses a spring by a distance before coming to rest. the coefficient of kinetic frictionbetween the block and table is (a) what is theinitial velocity (assumed horizontal) of the bullet? (b) whatfraction of the bullet’s initial kinetic energy is dissipated(in damage to the wooden block, rising temperature, etc.)in the collision between the bullet and the block? ​   ### Another question on Physics Physics, 31.01.2019 21:40
Plzzzz asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave Physics, 30.01.2019 16:00

Two students want to test whether the acceleration due to gravity is 9.8 m/s², as listed in their textbook. they dropped a ball and measured its velocity at different times. their results are in the table below. did the students' results support the textbook's value for acceleration due to gravity? a. no, the students found that the ball did not accelerate. b. no, the students found that the acceleration was 8.7 m/s². c. yes, the students' results agree with the textbook value of 9.8 m/s². d. no, the students found that the acceleration was 17.4 m/s².
