Question

Calculate the acceleration of the object during the first two seconds

Answer 1

Answer:

The acceleration of the object during the first two seconds  is 1.5 $\frac{m}{s^{2} }$.

Explanation:

At t = 2 s, velocity of the object is 3 m/s

At t = 0 s, velocity of the object is 0 m/s

Acceleration is define as rate of change of velocity with time.

∴Acceleration = $\frac{v_{f} -v_{i} }{t_{f} - t_{i} }$

Acceleration = $\frac{v_{2} -v_{0} }{t_{2} - t_{0} }$

Acceleration = $\frac{3-0 }{2-0 }$

Acceleration = 1.5 $\frac{m}{s^{2} }$

The acceleration of the object during the first two seconds  is 1.5 $\frac{m}{s^{2} }$.
