Answer:
speed: 35m/s
direction: left
Explanation:
Assuming the right side is the positive direction:
before explosion:
P = mv = 0
after explosion:
P' = 15P + 5P
(Set the velocity of the 15kg piece after explosion as v1' and the velocity of the 5kg piece after explosion as v2')
P' = 0.75mv1' + 0.25mv2'
P' = (15kg)v' + (5kg)(105m/s)
P' = 525kg/m/s + (15kg)v1'
P = P'
525kg/m/s + (15kg)v1' = 0
(15kg)v1' = -525kg/m/s
v1' = -35m/s
<u>speed = |-35| = 35m/s</u>
<u>direction is to the left since the right side is the positive direction.</u>
<span>The
number of cooling fins effect increases the rate of energy transfer from a
radiator. It is because the cooling fins have an enlarged area allows heat to
be transferred into the area away from the object it needs to have less heat
with. Thereby cooling the object with cooling fins.</span>
Answer:

Answer:
The equation for acceleration can be rewritten as B to calculate the net force acting on an object when its mass and acceleration are known.
Explanation:
I hope that helps! (B is the answer)
