Homework Statement
A 7000. kg plane is launched from a aicraft carrier in 2.0 sec. by a force of 350,000 N.
a) What is the plane's acceleration?
b)What is the plane's velocity after the two seconds?
Homework Equations
A=f/m => A=350,000/7000 = 50 m/s2

Now I think I got it =) well, I did the equation and got .2N as the remaining force, then I did the regular equation to find the mass.
m= ? ========> m=f/a ==> m=.2/.11= 1.8 kg
a= .11 m/s
f= .2N
Oh ok. So you mean that I need to add (the regular addition or in any other way?) the frictional force which is 2.6 and the force of 2.8, and then finish with the regular equation to find the mass?
Homework Statement
Because of a frictional force of 2.6N, a force of 2.8N must be applied to a textbook in order to slide it along the surface of a wooden table. The book accelerates at a rate of 0.11 m/s
a) What is the unbalanced force on the book?
b) What is the mass of the book...
