• If you use a cart with half the mass, you reach _______final speed.

Question

• If you use half the force, you reach ______ final speed.
• If you push twice as long, you cover _______ distance during pushing.
• If you use a cart with half the mass, you cover_______ distance during pushing.

Answer 1

If no friction, same force
half mass --> twice acceleration
v = a t so twice the speed in the same time

half

d = (1/2) a t^2
twice as long --> 4 timmes distance

a = twice with half the mass and same force
d = (1/2) a t^2
twice a ---> twice distance
