Answer:
Where were you given this question?
Step-by-step explanation:
This seems to be a bad question but if 3/5 is four, than 1/5 is 1.3333333333 etc.
I would advise to keep asking around if this doesnt help, if it does a thanks would be appreciated
Answer:
85
Step-by-step explanation:
take the absolute value of the coefficient (2)
then the lower bound is the negative of that (-2)
so the range is [-2,2]
Answer:
C. The cheetah runs 24.5 meters per second & D. The cheetah will run 1,470 meters in 1 minute
Step-by-step explanation:
First I did 196/8 to see how many meters the cheetah ran per second which got me 24.5 meters, so that simply gave me answer C. I then did process of elimination through the answers by taking 24.5 and multiplying it by however may seconds to see if it got the same distance that was in the answer. When I came to D. I had to do 24.5*60 (Because one minute is 60 seconds) which got that answer.
Step-by-step explanation:
first and foremost start off with a proper FBD (I drew in the forces and acceleration just to refer back to it quicker, assume right and up are positive)
a) F net = Forces aiding the movement - forces opposing
if the box is sliding to the right then we've got
Fnet = 26 + (-3)
[notice how I wrote that they're both being added because they're vector forces]
Fnet = 23 N
b) using Newton's second law of motion, F = ma, we can find the mass
Fnet = ma
rearrange for mass
M = Fnet/a
M = 23 N / 2.0 ms^-2
M = 11.5 Kg
