Both boats have same mass, blue boat speeds up from 2 km/h to 5km/h (Speed up by 3km/h). Red boat slows down from 10km/h to 5km/h (Slow down by 5 km/h). Which had greater force?
Red boat had a greater force because it had a greater change in velocity.

Why does the egg not crack when is collides with a sheet, but it does when it collides with a wall?
Impulse: The time of the collision is larger.

An empty shopping cart and a full shopping cart both increase speed by 2m/s. Which one experienced the greater force.
The full cart because it has more mass.

There is a collision between a bug and a car. The bug experiences a greater change in velocity because...
it has a much smaller mass

If a large semi truck and and a smart car collide, which will experience a greater change in velocity?
The smart car because a lesser mass needs less force to have a greater change in velocity.
