A stack of books rests on a level frictionless surface. A force F acts on the stack, and it accelerates at 3.0 m/s2. A 1.0 kg bo
ok is then added to the stack. The same force is applied, and now the stack accelerates at 2.0 m/s2.
1 answer:
Answer:
m1 = 2 kg
m2 = 3kg
Explanation:
The force can be getting by
F = m * a
F1 = F2
a1 = 3.0 m/s^2
a2 = 2.0 m/s^2
The force F1=F2 because the force is applied so get the a2 acceleration
m1 * a1 = m2 * a2
m2 = m1 + 1kg
m1 *(3.0 m/s^2) = m2* (2.0 m/s^2)
m1 *(3.0 m/s^2) = (m1 + 1kg) * (2.0 m/s^2)
m1*(3.0m/s^2-2.0m/s^2)=2 kg*m/s^2
Solve to find the mass
m1 m/s^2= 2 kg*m/s^2
m1 = 2 kg
m2 = 3kg
