Answer:
3.2 m/s²
Explanation:
Acceleration can be calculated as:
v = u + at (where v is final velocity, u is initial velocity, a is acceleration and t is time)
25 m/s = 9 m/s + a(5 s) (a is unknown)
16 m/s = a(5 s)
a = 3.2 m/s²
We assume that this is a uniform acceleration (meaning that the velocity increases at an equal rate for those 5 seconds).
The momentum after collision is given by (m1+m2)v where m1 is the mass of car A, m2 us the mass of car B while v is the common velocity after collision.
Therefore, momentum=(2000+4000)5=30000kgm/s to the right.
