Question

A coconut falls to the ground from a coconut tree within 2 second.

a) What is the acceleration of falling coconut ?

b) Find out the height of the coconut tree ?

c) Find out the velocity of the coconut just before it touches the ground ?​

Answer 1

Answer:

a) 9.8m/s²

b) 19.6m

c) 19.6m/s

Explanation:

a) The acceleration of the fall of the coconut will be equal to the acceleration due to gravity of the earth.

so, acceleration = 9.8m/s².

b) s = ut+gt²/2 (u = 0m/s)

s = 0×2 + (9.8×2²)/2 = 9.8×2 = 19.6m.

c) v = u+gt

v = 0+9.8×2 = 9.8×2 = 19.6m/s.
