The net force on the is zero.

The acceleration of the car is zero.

The net force acting on the car is greater than zero.

the skateboard applies a force on Moe, pushing him forward.

the curb applies a force on the skateboard, not on Moe.

the velocity of the skateboard is less than 10 m/s.

the curb also applies a force on Moe, accelerating him forward.

All will have the same acceleration.

It doubles (2 x greater)

It triples (3 x greater)

It's 6 times greater

It's one-third as much (⅓ as much)

It doubles (2 x greater)

It quadruples (4 x greater)

It halves (½ as much)

It quarters (¼ as much)

$a=\frac{F_{net}}{m}=\frac{2000}{4000}=0.5\ \frac{m}{s^2}$

$a=\frac{F_{net}}{m}=\frac{4000}{2000}=2\ \frac{m}{s^2}$

$F\ =\ ma\ =\ 2000\times4000=\ 8000N$

$a=\ \frac{F_{net}}{m}=\ \frac{4000}{2000}=0.5\ N$

 $F_{net\ }=ma=20\times2=40\ \frac{m}{s^2}$  

 $F_{net}=ma\ =20\times2=40\ N$  

 $a=\ \frac{F_{net}}{m}=\frac{40}{20}=2\ N$  

 $a=\ \frac{F_{net}}{m}=\frac{40}{20}=0.5\ \frac{m}{s^2}$

The bowling ball because its heavier so there is a greater force of gravity acting on the bowling ball so it will have a greater acceleration.

The feather because it has less mass so less inertia so it has less resistance to the force applied to it which makes it accelerate more.

They will hit at the same time because the ratio of weight to mass is the same for both objects so they will have the same acceleration. a = F/M = f/m

They will hit the ground at the same time because it's a magic trick.

The person will actually move backwards, they need to paddle the other way

The person is pushing harder than the water

The water pushes back with a greater force than the person
