A 3.0 kg block is initially at rest on a friction-less horizontal surface. The block is pulled with a constant horizontal net force of 4.8 N. Determine:
b) the time required for the block to reach a speed of 4.2 m/s. (Show all your work for 3

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
