Answer:
B
Explanation:
bIrish Kaleb picked Lucian usual
V0=0m/s (initially at rest)
t=6,7s
s=1/4mi=402,336m
s=(a*t^2)/2 -> a=2*s/t^2 -> a=2*402,336m/(6,7s)^2
a=804,672/44,89=17,93 m/s^2
<span>v=v0+at
</span>v=0+17,93 m/s^2 * 6,7s = 120,131 m/s = 432,4716 km/h
<span>21 is problematic as coal is legally a mineral resource but not geologically a mineral. That wouldn't be too bad if aggregate wasn't also legally a mineral resource but not geologically a mineral. </span>
Answer: 2.5m/s^2
Explanation:
Mass of car = 2250 kg
Force = 5625 N
Acceleration of the car = ?
Recall that Force is the product of mass of an object and acceleration by which it moves.
i.e Force = Mass x acceleration
5625 N = 2250 kg x acceleration
Acceleration = (5625 N / 2250 kg)
Acceleration = 2.5m/s^2
Thus, the acceleration of the car is 2.5 metres per second square.
