Answer 2

Answer:

Acceleration of the typhoon is 15 km/h².

Explanation:

Given,

Velocity of the typhoon, v₁ = 180 km/h

Velocity of  the typhoon when it reaches the Bulacan, v₂ = 210 km/h

Time taken by the typhoon to hit Bulacan, t = 2 hours

Acceleration of the typhoon, a =?

As we know,

Acceleration of an object is defined as the rate of change in velocity of an object per of unit time.

• $a = \frac{v_2 - v_1}{t}$
• $a = \frac{210 - 180}{2}$
• $a = \frac{30}{2}$
• a = 15 km/h²

Hence, acceleration = 15 km/h²
