Question

a) What is the relationship between force applied on a body and the resulting acceleration caused in it?
(b) A force produces an acceleration of 5 m s’2 when applied on a body of mass 2 kg. Find the magnitude of force. How much acceleration will the same force produce when applied to a body of mass 4 kg?

Answer 1

Answer:

a) Relationship between force and acceleration is F=ma.

b) given the first part of question as

acceleration= 5m /s2

m= 2 kg

F = ma= 2x5 =10 N.

Now in the second part the following is given...

acceleration=?

Mass=4 kg

force = 10 N from the first part of the question..

we know that

F= ma

a= f/m

a= 10/4

a=2.5 m/ s2..

hope this will be useful
