Answer:
Answer is 3
Step-by-step explanation:
x/3-2x/1+3 =x-3/5
x/3-x/3 = x-3/5
0=x-3/5
0=x-3
3=x
sothat, x = 3 ans
we have M is durectly porpotional to r^2
so M=(k)r^2
and when r=2, m=14
so 14=(k)(2)^2
k=14/4 =7/2
so when r=12
m= (7/2)(12)^2 =(7/2)(144) = 504
Answer:
The average acceleration of the cyclist was 0.6 m/s².
Step-by-step explanation:
Acceleration:
The rate change of velocity per unit time is call the acceleration of the object.
u= initial velocity
v= final velocity
t= time taken change of velocity.
During the final 5 seconds of a race cyclist increased her velocity from 4m/s to 7 m/s
Here v= 7 m/s and u=4 m/s t=5 seconds
=0.6 m/s²
The average acceleration of the cyclist was 0.6 m/s².
Answer:
Frankly, substitution is almost always a better method. Graphing is a very precise and time consuming process where you have to calculate several..
