Answer:
Therefore, the initial velocity of zombie is 19.2 m/s.
Explanation:
Given:
The acceleration of motion of zombie is [tex]a=6.1 \rm{m/s^{2}}[/tex]
Zombie accelerates for [tex]t=7\rm{s}[/tex]
The distance covered by the zombie is [tex]s=15\rm{m}[/tex]
To find the initial velocity [tex]u[/tex] of the motion, use the second equation of motion,
[tex]s=ut+\frac{1}{2}st^{2}[/tex]
[tex]15=u\times7+\frac{1}{2}6.1\times(7)^{2}\\u=-19.2\rm{m/s}[/tex]
Therefore, the initial velocity of zombie is 19.2 m/s.
