Physics pair SW and other HWs

Eto yung physics seatwork kanina:


Bullet Strikes Wooden Block. A 5.20 g bullet moving at 672 m/s strikes

a 700. g wooden block at rest on a frictionless surface. The bullet

emerges, traveling in the same direction with its speed reduced to 428 m/

s. What is the resulting speed of the block?

Billiard Ball. A billiard ball moving at a speed of 2.2 m/s strikes an

identical stationary ball with a glancing blow. After the collision, one ball is

found to be moving with a speed of 1.1 m/s in a direction making a

60.° angle with the original line of motion. Find the velocity of the other


Ice-Skating Man. A 60 kg man is ice skating due north with a velocity of

6.0 m/s when he collides with a 35 kg child. The man and the child stay

together and have a velocity of 3.0 m/s at an angle of 35° north of east

immediately after the collision. What are the magnitude and direction of

the velocity of the child just before the collision?


ayan… due tomorrow. Dali lang yan. Just remember what sir said.

May english quiz daw bukas. Study well for the math speed test and bio LT. BTW, make sure tapos nyo na yung SS hw. Baka (baka lang), i-collect ni ma’am bawagan bukas yung fillers. GOOD LUCK!


*edit kung may kulang*



  1. May math hw din tayo. May iproprove. Post ko mamaya kung walang may kopya
