Linear Momentum and Second Law of Motion: Practice Problem & Solution

The linear momentum of a particle is given by P = a + bt², where t is time and a & b are constants. The force acting on the body is directly proportional to :
t°
t
t²
t³

Solution Explained:

To solve this problem, we apply the core principles of Linear Momentum and Second Law of Motion. Understanding the underlying formula is key to arriving at the correct answer below:

Given momentum of the object is P = a + bt²;

Force is defined as rate of change of momentum F= dP/dt= 2bt. so Force is proportional to t.
