A 1.3 N force is used to push a 2 kg block across a frictionless surface. What is the acceleration of the block caused by this force? Report your answer to 2 decimal places.

Answer 1

Greetings! Lets solve this shall we ?

So, we must find the acceleration of the block such that F = mass times acceleration! Then,

F = ma

1.3 = 2a..............We divide 2 to both sides such that

a = 0.65 m/s²

I hope this helped!

Answer 2

Use Newton's 2nd law:

F = ma

a = F/m

You know F and m, so plug in the numbers and solve for a.

Answer 3

Since the surface is frictionless and horizontal (no mention of angle), once the initial force is removed there will be no acceleration on the block because there is no net force acting on the system (block).

a=F/m

a=0/2

a=0
