A certain force causes an object to acceleration with an acceleration of 6.85 m/s/s. If the mass is increased by a factor of 2.64 and the force is increased by a factor of 3.85 , what is the new acceleration that the object will experience?

Answer 1

F=m*6.85
F*3.85=2.64*m*a

solve for a

a=m*6.85*3.85/(2.64m)

check my reasoning

Answer 2

Remember that F = m a ;
therefore, a = F/m.

If F' = 3.85 F and m' = 2.64 m
The new acceleration is:
a' = F'/m' = (3.84/2.64)*(F/m)

= 1.455 F/m = 1.455 a

Complete by inserting the original value of a.
