Answer:
100-0 / 6 = 16.66 m/s
Explanation:
acceleration = vf-vi / time
vf= 100m/s
vi= 0 m/s
t= 6s
Answer: 39.5 N
Explanation:
2 x force x static friction coefficient = weight (weight=2μsF)
force = ?
static friction coefficient = 0.416
weight = 32.9N
substituting the values above into the equation we get
2 x F x 0.416 = 32.9
F = 32.9 / (2 x 0.416)
F = 39.5N
So Neon ( Ne) is the correct answer.
So, acceleration is the change of velocity in time. If no vectors are used, one can use speed:
a = (final speed - start peed)/ time = 10/5= 1 m/s^2,
Notice that the units are m/s^2, or (m/s)/s. That is speed (m/s) per unit time (s)
