### Question

A palm fruit dropped to the ground from the top of a tree 45m tall. How long does it take to reach the ground? (g = 10ms-2)

### Options

A) 9s

B) 4.5s

C) 6s

D) 7.5s

E) 3s

The correct answer is E.

### Explanation:

Using the equation of motion

S = ut + $$\frac{1}{2}$$at2

45 = (0 x t) + ($$\frac{1}{2}$$ x 10 x t2)

t = 3s

## Dicussion (1)

• Using the equation of motion

S = ut + $$\frac{1}{2}$$at2

45 = (0 x t) + ($$\frac{1}{2}$$ x 10 x t2)

t = 3s
