Answer: Yes. Please find the answer in the explanation.
Explanation:
Yes. Since velocity is a vector quantity, that is, it has both magnitude and direction.
If the displacements covered are not of the same direction, the velocity will not also of the same direction.
Take for instance, if the velocity in a positive is 40 m/s and velocity in the opposite direction is - 20 m/s . Then, the resultant velocity will be 40 - 20 = 20 m/s
Therefore, it is possible that at any time during their trip their velocity was -20 m/s.
Ф = 1/2αt²
s = rФ
s = 1/2αrt²
s distance
α = 3 rad/s²
t = 2 s
r = 0.5 m
An ice block will go further because there is less friction between the table and the ice. The brick has more friction, weight, and a gritty texture, so it won't make it as far. As for the ice block has less friction, a smoother surface, and a smoother texture which makes it have less friction.
Answer:
f the mass of an object increases, predict what will happen to the coefficient of sliding friction. The coefficient of sliding friction will increase. The coefficient of sliding friction will decrease.
Explanation:
No it cannot because you would have to test it over and over again to make sure it was correct the first time.
