Answer:
6.7 /s.
Step-by-step explanation:
Initial velocity = u m/s
From the question, final velocity, v = - 2u m/s
Note - (the minus sign indicates that the direction was reversed and doubled)
t = 0.45
From equation of motion,
v = u + at
Acceleration, a = (v - u)/t
= (-2u - u)/0.45
= - 3u/0.45
Acceleration, a/Original speed, u = 3/0.45
= 6.7 /s
4 out of 10 because the amount of prime numbers from 1- 10 is
2, 3, 5, and 7.
Hope this helps!
slope intercept form = y=mx +b
where m would be the slope and b is the y intercept
equations would be:
cool cars: y = 179x +1999
awesome autos: y = 249x
31 quarts, because there are 4 quarts in a gallon
The probability is 4:20
