Average acceleration = (change in speed) / (time for the change)
Average acceleration =
(speed at the end of the 14 seconds) / (14 seconds)
All subspecies of leopards can be found throughout Asia south Asia and India. except for African leopards
Answer:
4 s
Explanation:
u = 19.6 m/s, g = 9.8 m /s^2
Let the time taken to reach the maximum height is t.
Use first equation of motion.
v = u + at
At maximum height, final velocity v is zero.
0 = 19.6 - 9.8 x t
t = 19.6 / 9.8 = 2 s
As the air resistance be negligible, is time taken to reach the ground is also 2 sec.
So, total time taken be the ball to reach at original point = 2 + 2 = 4 s
