Question
An object of mass 16 kg is moving with an acceleration of 3 m/s2. Calculate the applied force. If the same force is applied to an object of mass 24 kg, how much will be the acceleration?
Solution
Given: m1 = 16 kg, a1 = 3 m/s2, m2 = 24 kg
Find: a2 = ?, F = ?
Applied force, F = m1a1 = 16 kg × 3 m/s2 = 48 N
∴ F = m2a2
∴ Acceleration, `"a"_2 = "F"/"m"_2`
`= (48 "N")/(24 "kg")`
= 2 m/s2
