Question

select the correct answer. a carmaker has designed a car that can reach a maximum acceleration of 12 meters/second². the cars mass is 1,515 kilograms. assuming the same engine is used, what should the cars mass be if the carmaker wants to reach an acceleration of 15 meters/second²? use f = ma. a. 1,212 kg b. 1,335 kg c. 1,466 kg d. 1,515 kg e. 1,894 kg

Explanation:

Step1: Calculate initial force

$F = m_1 \cdot a_1 = 1515 \cdot 12 = 18180\ \text{N}$

Step2: Find new mass with same force

$m_2 = \frac{F}{a_2} = \frac{18180}{15} = 1212\ \text{kg}$

Answer:

A. 1212 kg
