Answer: Mass of car is 2660kg
Explanation:
Use equation for Kinetic ene)rgy :
Ek=(m*V²)/2
from this eqation you can get mass
m*V²=Ek*2
m=Ek*2/v²
Ek=5.32*100000J
V=20m/s
m=?
m=2*5.32*100000J/(20m/s)²
m=2660kg or 2.66t
The atomic mass of this question is 10.811
Time and velocity are both vectors T/F
(60 * 546) / 110 = 297
297 hrs.
