(a) impulse = F x t = m x a x t
therefore: -32.4 = 0.4* (a) * t (minus since it is in the negative direction)
-32.4 = 0.4 (a) * 0.034
-32.4 = 0.0136a
a = -2382.4 m/s2
and Using kinemtaic equations : v = v0 + at
v = 16 - 2382.4(0.034)
v = -65 m/s The minus represent its direction,(in the negative direction )
(b) Avg Force = impulse/ time = 32.4 / 0.034 = 952.95 N
