Answer: 90 words per minute
====================================================
Work Shown:
270 words : 3 minutes
270/3 words : 3/3 minutes ..... divide both parts by 3
90 words : 1 minute
Brayden can type 90 words per minute (wpm).
First find the mass.
Since weight force is 48N, and acceleration due to gravity is 9.8 m/s^2,
weight force = mass*acceleration due to gravity,
mass = weight/acceleration
mass = 48N / 9.8 m/s^2
mass = 4.9 kg
Now you find the force needed to accelerate to 3.0 m/s^2.
Force = mass*acceleration
Force = 4.9kg * 3.0 m/s^2
Force = 14.7 N
If it has the negative so the answer will be negative but if it doesn't have the negative so the answer is positive because if you want to find the m you should divide the both sides of the equation by the factor of m:
-4m = 1.75 ⇒ -4m/-4 = 1.75/-4 ⇒ m = 1.75/-4 ⇒ m = -0.4375
4m = 1.75 ⇒ 4m/4 = 1.75/4 ⇒ m = 1.75/4 ⇒ m = 0.4375 :)))
i hope this is helpful
have a nice day
M=y2-y1/x2-x1 m=(-3-13)/(9-7) m=-16/2
m=8
