M1u1 + m2u2 = m1v1 + m2v2
2 * 3 + 1 * 0 = 2 * 1 + 1 * v2
6 = 2 + v2
v2 = 6 - 2 = 4 m/s.

Rewrite Newton's first law of motion in your own words.
BlackZzzverrR [31]

Vlad1618 [11]

Answer:

a) 16m/s b) 192m

Explanation:

v1=32m/s a=-2m/s^2 t=8s v2=? d=??

a) I will use this equation v2= v1 + a*t

v2= 32m/s + -2m/s^2 * 8s

v2= 32m/s + -16m/s

v2= 16m/s

b) v2^2=v1^2 + 2ad

rearranging

v2^2-v1^2=2ad

v2^2-v1^2/2= a d

v2^2-v1^2/2a=d

16m/s^2 - 32m/s^2/ 2 x-2m/s^2 =d

d=192m
