Answer:
a 15.22 m/s
b 45.65 m
Explanation:
Using the same formula,
x = vt, where
x is now 45.65, and
t is 3 s, then
45.65 = 3v
v = 45.65/3
v = 15.22 m/s
See the attachment for the part b. We used the distance gotten in part B, to find question A
2. A woman pulls a 20 kg suitcase along a 15 m corridor using a horizontal force of 50 N.

Answer:
c, 280,000J
Explanation:
You should use the equation KE (Kinetic Energy) =
m = 2500
v = 15
KE =
KE = 281250 Joules.
This is consistent with the answer B, as all of the parameters given to you are rounded to 2 significant figures so naturally, the answer should also be rounded to 2 sig figs.
KE = 280,000 J
