Question

An unloaded truck weighing 2000kg has a maximum acceleration of 0.5m/s². what is the maximum acceleration when it is carrying a load of 2000kg?​

Answer 1

Answer:

0.25 m/$s^2$

Explanation:

Mass of truck when unloaded ($m_u$) = 2000 kg

Acceleration of truck when unloaded ($a_u$) = 0.5 m/$s^2$

$F = ma = m_ua_u\\F=2000*0.5 = 1000N$

Mass of truck when loaded ($m_l$) = 2000 + 2000 kg = 4000 kg

$F = ma\\F = m_la_l\\1000 = 4000 * a_l\\a_l = \frac{1000}{4000} = \frac{1}{4} = 0.25 \ m/s^2$
