Homework Statement
A block of mass M = 10 kg is sitting on the table as shwoin Figure above. There is friction between the block and the table, the coefficient of friction is u = 0.1.
The block has initial velocity V, and a constant forceF is applied to the black as showing Figure above.
A) For the case of V = 0 and F = 5 N, find acceleration of the block
B) Constant force is F = 5N, and at time t = 0, the initial velocity is v = 2 m/s, find acceleration of the block.
C) Constant force is F = 15N, and at time t = 0, the initial velocity is v = 2 m/s find acceleration of the block.
It asks to find the dependence of velocity and position as functions of time, but I assume i just integrate to find those.
Homework Equations
ΣF=ma
Ff=μN
The Attempt at a Solution
F0-Ff=10kg(a)
a=(5N-10N)/10kg; a=0
So I think the acceleration is 0 in both cases, but I'm uncertain if the initial velocity would have an effect. Assuming I derived a correctly V0 doesn't affect a, but I'm honestly not sure.
