The mass of the heavier block is 24 kg and the mass of the lighter blocks is 12 kg and the magnitude of the force of the connecting string on the smaller block is 19 n. assume: g = 9.8 m/s 2 and the horizontal surface on which the objects slide is frictionless. 12 kg 24 kg 19 n f determine the force f. answer in units of n.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?

What are similarities and differences between refraction, reflection, diffraction and absorption?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
