Answer:
x = 2.044 m
Explanation:
given data
initial vertical component of velocity = Vy = 2sin18
initial horizontal component of velocity = Vx = 2cos18
distance from the ground yo = 5m
ground distance y = 0
from equation of motion
solving for t
t = 1.075 sec
for horizontal motion
x = 2cos18*1.075
x = 2.044 m
<u>Answer: </u>
Cat has 2.02 seconds to right itself.
<u>Explanation: </u>
Initial height of cat from ground = 20 meter.
We have equation of motion , , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
In this the velocity of cat in vertical direction = 0 m/s, acceleration = acceleration due to gravity = 9.8 , we need to calculate time when s = 20 meter.
Substituting
So, cat has 2.02 seconds to right itself.
