Question 20 (4 points)

Listen
When a net horizontal force of 250 N acts on a 50-kg cart that is free to roll on a
level surface,
A) the cart accelerates at 9.8 m/s².
B)
the cart accelerates at 0.20 m/s².
C)
the cart accelerates at 5 m/s².
D)
the cart accelerates at 12500 m/s².
E)
the cart does not accelerate because it pushes back on the person with a
force of 250 N.

Answer 1

Step-by-step explanation:

C is correct.

Newton second law states that force is directly proportional to acceleration with m being the constant of variation.

`f _(net) = m(a)`

So

`250 = 50(a)`

`a = 5`

A is wrong, the constant g only happens in free fall or in vertical direction

B and D are wrong due to the mathematical error or equation error
