A force of 20 N accelerates a 2 kg object. How much force is needed to give the same acceleration to a 20 kg object?

Answer 1

The force required is #"200 Newtons"#.

Apply the formula.

#F = ma#
to solve this problem. In the case of the #"20 N"# force, we have
#"20 N" = "2 kg" xx a#

thus

#a = "10 m/s"^2 -># read this as #10# meters per second squared, or #10# meters per second every second
Applying the formula again in case of the #"20 kg"# object, we have
#F = ma#
#F = "20 kg" xx "10 m/s"^2#
#F = "200 N"#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
