Ablock of mass m 13 kg slides along a horizontal surface (with friction, μ,-0.31) a distance d= 2.55 m before striking a second block of mass m2-9.75 kg.
the first block has an initial velocity of v 7.75 m/s.

randomized variables :
m1 = 13 kg
m2 = 9, 75 kg
μ,-0.31
d-2.55 m
v=7.75m/s m2

a) assuming that block one stops after it collides with block two, what is block two's velocity after impact in m/s?
numeric: a numeric value is expected and not an expression.

(b) how far does block two travel, d in meters, before coming to rest after the collision?
numeric: a numeric value is expected and not an expression.
