Question

The 100 kg block takes 6.00 s to reach the floor after being released from rest. What is the acceleration of the block?

1) 9.8 m/s²
2) 16.7 m/s²
3) 25.0 m/s²
4) 36.0 m/s²

Answer 1

The block has an acceleration of 0 m/s².

Step-by-step explanation:

To find the acceleration of the block, we can use the kinematic equation:

v = u + at

Where v is the final velocity, u is the initial velocity (which is 0 in this case), a is the acceleration, and t is the time.

Since the block is released from rest, the initial velocity is 0, and the final velocity is the velocity when it reaches the floor. We can assume the floor is at rest, so the final velocity is also 0. Therefore, the equation becomes:

0 = 0 + a(6.00)

Simplifying this equation, we can solve for a:

a = 0 / 6.00 = 0 m/s²

So, the acceleration of the block is 0 m/s².
