A 50 g bullet at 50 m/s hits a block 2.0 m away. The coefficient of friction is 0.30. What is the force of bullet on the block, the velocity of the block and bullet and distance traveled by the block? Assume this is a perfectly inelastic collision.
Known: m_b = .0050kg
v_b = 50. m/s
d_b = 2.0 m
μ = 0.30
p_1 = p_2
F = ma
μ = -a/g
The Attempt at a Solution
A) 0.30 = -a/9.8
I feel like this isn't right for some reason...would this give me the correct acceleration?
B) (.0050kg)(50 m/s)=(m_1 + m_2)v
Since it's perfectly inelastic, can't I assume that v is the same for the block? Is that how I'd find m2?
C) I would be able to solve for distance once I have the velocity.
