A 0.07 kg bullet traveling at speed hits a 13.6 kg block of wood and stays in the wood. The block with the bullet imbedded in it moves forward with a velocity of 7.7 m/s. What was the velocity (speed) of the bullet immediately before it hit the block (in m/s)

What is the final velocity of the initial velocity of 25 and -50?

Which statement is best supported by the information in the chart? wave y is moving the fastest. wave x is moving the fastest. all of the waves are moving at the same speed. all of the waves have the same value of wavelengths per second.

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
