A 35 g bullet with a velocity of 75 m/s hits a 7 kg block and the bullet goes inside the block. The block moves and compresses the spring. Find the maximum compression on the spring where the block momentarily comes to a stop. The spring constant is 25 N/m.

Which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
