A3 kg mass at rest on the floor is attached to a string which goes vertically to a pulley. a weight is attached to the other end of the string and released. if the 3 kg mass rises 50 cm in 1 s, find is the value of the other mass.

M = 3.68 Kg

Explanation:

given,

mass on the floor, m = 3 Kg

mass raised to, s = 50 cm

time,t = 1 s

using equation of motion

s is the displacement .

initial speed = 0

   a = 1 m/s²

acceleration in terms of mass and gravity is given as

 a = m g

M is the mass of the block hanging

     M + 3 = 9.8 M - 29.4

      8.8 M = 32.4

       M = 3.68 Kg

The other mass is equal to M = 3.68 Kg

answer; ///(74) degrees is your answer..

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
