Question

A coconut drops from the top of a palm tree 2m high. If air current is neglected , how long will it take the coconut to reach the ground (take g as 10N/KG

Answer 1

To solve for the time it takes for the coconut to reach the ground, we can use the equation of motion:

s = ut + (1/2)at^2

Where:
s = distance fallen (2m)
u = initial velocity (0 m/s)
a = acceleration due to gravity (10 m/s^2)
t = time taken

Plugging in the values we have:

2 = 0*t + (1/2)*10*t^2
2 = 5t^2
t^2 = 2/5
t = sqrt(2/5)
t = sqrt(0.4)
t = 0.63 seconds

Therefore, it will take approximately 0.63 seconds for the coconut to reach the ground.
