Metalowy prostopadłościan o objętości 30 cm3 zawieszono na siłomierzu, który wskazał 3 N. Jakie będą wskazania siłomierza po całkowitym zanurzeniu prostopadłościanu w wodzie? Gęstość wody wynosi 1000 kg/m , a wartość przyspieszenia ziemskiego 10 n/kg

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)

A26 cm object is 18 cm in front of a plane mirror. a ray of light strikes the object and is reflected off the mirror at a 42-degree angle. what is the angle of reflection? degrees what type of image is formed? what is the size of the image? cm

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?
