Answer:
Explanation:
Givens
Vi = 10 m/s
Vf = 40 m/s
a = 3 m/s^2
Formula
a = (vf - vi) /t Substitute the givens into this formuls
Solution
3 = (40 - 10) / t Multiply both sides by t
3*t = t(40 - 10)/t Combine. Cancel t's on the right
3*t = 30 Divide by 3
3t/3 = 30 / 3
Answer: t = 10 seconds.
The significant figures also known as the significant digits or precision of a number written in positional notation are digits that carry meaningful contributions to its measurements
Ok I don’t know the answer I’m in 5th grade but 2431 is wrong
Answer:
e) True Yes both are constant
Explanation:
Let us propose the solution of the problem before reviewing the statements, we use Newton's second law
F - fr = m a
N- W = 0
N = mg
The equation for the force of friction is
fr = μ N
F - μ mg = m a
F = m (a- μ g)
Now let's review the claims
.a) False. Normal force and friction are constants.
.b) False. Both are constant.
.c) False. Both are constant.
d.) False
e) True Yes both are constant
