Physics

To solve this problem, we need to use the relationship between momentum, velocity, and the time required for the object's momentum to become 16 kg·m/s.

 

Write the formula for momentum

Momentum is given by:

Where:

(desired momentum)

(mass of the object)

is the velocity of the object at the time the momentum becomes 16 kg·m/s

 

Thus, we can solve for the velocity at that time:

 

Use the kinematic equation to find the time

The object's velocity is decreasing due to deceleration, so we can use the following kinematic equation:

Where:
