The 6 kg block is then released and accelerates to the right, toward the 4 kg block. the surface is rough and the coefficient of friction between each block and the surface is 0.3 . the two blocks collide, stick together, and move to the right. remember that the spring is not attached to the 6 kg block. find the speed of the 6 kg block just before it collides with the 4 kg block. answer in units of m/s.

v =3.41 m/s

Explanation:

given,

mass of block 1 = 6 Kg

mass of another block 2 = 4 Kg

coefficient of friction = 0.3

Assuming 6 Kg block is attached to the spring of spring constant 350 N/m

and distance between the two block is equal to 0.5 m

using formula

   U = 43.75 J

using conservation of energy

 KE = U - f.d

where f is the frictional force acting

       v =3.41 m/s

i would think form in reponse to tensional forces

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
