a. the ship's momentum: 60,000 kg m/s

b. two actions to reduce ship's momentum: reduce the mass and speed of the ship

Further explanation

Momentum is generally possessed by moving objects.

Momentum is the product of the mass and the velocity of an object

Can be formulated:

p : momentum (kg.m/s)

m : mass (kg)

v : velocity (v)

From this formula it can be concluded that momentum is directly proportional to the mass and velocity of the object

If 2 objects collide with velocity va and vb, then the law of conservation of momentum will occur:

mava + mbvb = mava '+ mbvb'

the total momentum before and after the collision is equal (in the absence of external forces)

Collisions can be elastic, inelastic, and completely inelastic (the colliding objects stick together)

Given

a 2000 Kg ship is sailing at a velocity of 30 m/s

Required

a. the ship's momentum

b. two actions could the ship take to reduce its momentum

Solution

a. the ship's momentum

b. two actions to reduce ship's momentum

Because momentum directly proportional to the mass and velocity of the object, then the actions that can be taken are:

• 1. reduce the load/mass of the ship by removing some of the objects on the ship
• 2. reduce the speed of the ship by braking / slowing down the ship
