The forces on the mass on the table are balanced because it moves at constant speed. The force to the right is 2mg, the force to the left must also be 2mg. The weight on the left is 1mg so the friction force on the mass on the table is also 1mg to the left.
Answer:
Explanation:
In space, rockets zoom around with no air to push against. ... When a rocket shoots fuel out one end, this propels the rocket forward — no air is required. NASA says this principle is easy to observe on Earth. If you stand on a skateboard and throw a bowling ball forward, that force will push you and the skateboard back.
38*10=380 N
To be more exact, 38 should be multiplied by 9.8 instead of 10.
Answer:
third
Explanation:
for every action there is an equal and opposite reaction
example
bouncing ball
ball receives a force from the ground due to collision
that same force causes the ball to bounce off the ground
first law:
inertia
example
stuff in space doesn't move unless its pushed
then it keeps going unless something stops it
second law
force = mass times acceleration
example
harder you push a cart the faster it goes
the less a cart weighs the faster a cart goes
