Question

An object initially at rest experiences an acceleration of:

a) 0 m/s²
b) 9.8 m/s²
c) 2 m/s²
d) 5 m/s²

Answer 1

The correct answer is c) 2 m/s².

Step-by-step explanation:

The correct answer for an object initially at rest experiencing an acceleration is c) 2 m/s².

Acceleration is the rate at which velocity changes over time. If an object moves from rest to a final velocity of 2 m/s in 1 second, the average acceleration can be calculated using the formula acceleration = (final velocity - initial velocity) / time. In this case, the initial velocity is 0 m/s, the final velocity is 2 m/s, and the time is 1 s. Substituting these values into the formula, we get:

acceleration = (2 m/s - 0 m/s) / 1 s = 2 m/s²
