Assuming the deer's acceleration was constant, we have

\Delta x=\dfrac{v_f+v_0}2t

where \Delta x is the deer's total displacement, v_f,v_0 are the deer's final and initial velocities, and t is time. Then

63.5\,\mathrm m=\dfrac{13.38\,\frac{\mathrm m}{\mathrm s}+3.29\,\frac{\mathrm m}{\mathrm s}}2t

\implies t=7.62\,\mathrm s

kotykmax [81]
<h3>Question -:</h3>

The Earth orbits around the sun because the gravitational force that the sun

exerts on the Earth:

O A. causes Earth's acceleration toward the sun.

O B. is very small because the sun is so far from the Earth.

O c. is smaller than the force the Earth exerts on the sun.

O D. pushes the Earth away from the sun.

<h3>Answer -:</h3>

O A. causes Earth's acceleration toward the sun.

A girl throws a rock horizontally at 10 m/s from the top of a building, 22 m above street level. Assuming free fall conditions a
MAXImum [283]

Answer:21.18 m

Explanation:

Given

initial speed u=10 m/s

height of building h=22 m

time taken to complete 22 m

h=ut+\frac{1}{2}at^2

initial vertical velocity =0

22=\frac{1}{2}gt^2

t=\sqrt{\frac{22\times 2}{g}}

t=2.11 s

Horizontal Distance moved

R=u_x\times t

R=10\times 2.11

R=21.18 m
