Henrietta is jogging on the side-walk at 3.05 m/s on the way to her physics class. Bruce realizes that she forgot her bag of bag
shusha [124]

Answer:

12.9121148614 m/s

35.9393048982 m

Explanation:

t = Time taken

u = Initial velocity

s = Displacement

a = Acceleration

g = Acceleration due to gravity = 9.81 m/s² = a

s=ut+\frac{1}{2}at^2\\\Rightarrow 38=0t+\frac{1}{2}\times 9.81\times t^2\\\Rightarrow t=\sqrt{\frac{38\times 2}{9.81}}\\\Rightarrow t=2.78337865516\ s

Time taken for the bag to fall is 2.78337865516 seconds

Time she has been jogging for

9+2.78337865516 = 11.78337865516 seconds

Total distance traveled by her

s=vt\\\Rightarrow s=3.05\times 11.78337865516=35.9393048982\ m

Henrietta is 35.9393048982 m away

Velocity of throwing

\dfrac{35.9393048982}{2.78337865516}=12.9121148614\ m/s

The velocity of throwing is 12.9121148614 m/s

A car traveling in a straight line has a velocity of 3.29 m/s at some instant. After 4.99 s, its velocity is 8.29 m/s.
seraphim [82]

Use the definition of average acceleration:

<em>a</em> = ∆<em>v</em> / ∆<em>t</em>

We have

<em>a</em> = (8.29 m/s - 3.29 m/s) / (4.99 s)

<em>a</em> = 1.002 m/s²

Alchen [17]

Answer:

in a free market system supply and demand forces affect the production and consumption decisions. There is little to no government control in such a system .

Explanation:

A free market is an economic system in which prices are based on competition between private actors and are not affected by other factors besides supply and demand, that is, where there are no external variables that condition the market.

Free market economy systems are characterized by limited government intervention, which characterizes democratic, liberal states and the modern global economy, in which the market in its private face makes most of the economic decisions, leaving the government a minimum amount of necessary regulations.
