A child’s toy arrow is launched horizontally from a bow at a speed of 8 m/s from a second story window 4 meters above the ground
Westkost [7]
First find the time it takes to hit the sand t
using s=1/2 g t^2
t^2= 8/9.8= 0.82 seconds
This means the sand was s = 8 * 0.82 = 6.5m away
The horizontal speed stays constant at 8 m/s
The vertical speed =.82 * 9.8 = 8.0 m/s
As the two velocities are equal the angle must be 45 degrees to the horizontal

Anna pushes a box with a force of 8.00 newtons. she generates a power of 3.00 watts. how much time does it take for anna to move
mote1985 [20]

The time  taken for anna to move the box the distance of 9.72 meters is 25.9 seconds. The correct option is c.

<h3>What is force?</h3>

The force is the action of push or pull to move or stop an object.

Anna pushes a box with a force of 8.00 newtons. she generates a power of 3.00 watts.

Force is related to power by the relation

Force = Power / Velocity

Put the values, we get

8 = 3/V

V = 0.375 m/s

Velocity is defined as the ratio of distance and the time taken.

The box is moved by the distance of 9.72 meters. So, time taken is

V = d/t

0.375 = 9.72/t

t =25.9 seconds.

Thus,  time  taken for anna to move the box the distance of 9.72 meters is 25.9 seconds.
