Answer: 0.28 m/s


Let

M1 = mass of Steve
V1 = velocity of Steve
M2 = mass of can
V2 = velocity of can

Because momentum is a conserved quantity:

P1 - P2 = 0

So

M1*V1 - M2*V2 = 0

78.0kg(V1) - 2.5kg(8.7m/s) = 0

78.0(V1) = 21.75

V1= 0.28 m/s

near the surface of the earth, objects in free fall (but not terminal velocity) experience a. constant distance. b. constant acc
Alenkasestr [34]
<h3><u>Answer;</u></h3>

B. constant acceleration.

<h3><u>Explanation</u>;</h3>
  • Free fall is the type of motion of a body or an object when only gravity is acting on it.
  • <em><u>All objects undergo free fall on the earth surface at the same rate irrespective of their mass. This is because the gravitational field on the surface of the earth 9.8 N/kg, causes and acceleration equivalent to 9.8 m/s/s of any object in free fall motion.</u></em>
  • Therefore,<u> the acceleration of any freely falling object near the surface of the earth is 9.8 m/s².</u>

How do air mass conditions ahead of the squall line support the development of new cell?
IRISSAK [1]
<span>Storm cells in a squall line typically move from the southwest to the northeast, and as the mature cells in the northeast begin to die off, new ones are formed at the opposite end to advance the line. The air in the southwest corner has strong vertical updrafts that allow new cells to grow and develop into thunderstorms.</span>
