Question
( 8c5p79) A certain force gives mass m1 an acceleration of 11.5 m/s2 and mass m2 an acceleration of 3.6 m/s2. What acceleration would the force give to an object with a mass of (m2-m1)?Tries 0/8 What acceleration would the force give to an object with a mass of (m2+m1)?

Tries 0/8 Tries 0/8
Explanation / Answer
Force F = m1 * 11.5 = 3.6* m2
Object with mass = m2 - m1
Acceleration = F/ ( m2 - m1 ) = 11.5m1 / ((11.5/3.6)m1 - m1) = 11.5 / (11.5/3.6 -1) = 5.24 m/s2
Object with mass m2 + m1
Acceleration = F/ (m1 + m2) = 11.5/(11.5/3.6 + 1) = 2.74 m/s2
