Answer:
From first Newton's equation of motion:
Substitute the variables:
Acceleration is 2 ms-²
Answer:
yes
Step-by-step explanation:
y + 4 = 12
Subtract 4 on both sides,
y + 4 - 4 = 12 - 4
y = 8
I'm assuming that the figure formed in this problem is a right angle. Thus, we need to use the Pythagorean theorem to get the distance or the hypotenuse.
Length = 20 meters
Height = 16 meters
a² + b² = c²
(20m)² + (16m)² = c²
400m² + 256m² = c²
656m² = c²
√656m² = √c²
25.61 m = c
The distance is 25.61 meters.
Answer:
A. x = 1/2at²
Step-by-step explanation:
Among the equations, the equation that is dimensionally consistent is x=1/2at² where;
x is the distance in meters (dimension is length (L))
a is the acceleration in m/s² (dimension is L/T²)
t is the time in seconds (s) (dimension of time is T)
Substituting the dimensions into the formula to check if we are going to arrive at the dimension for distance;
1/2at² = 1/2(L/T²)T²
= 1/2× L/T² × T²
= 1/2 × L
Since L which is the resulting dimension is the dimension for distance (x), this means that the equation x = 1/2at² is dimensionally consistent.
Answer:
B
-3
Step-by-step explanation:
B is correct but based on the fact that you selected it I'll assume you know why (comment if you want me to explain it)
Then for two lines to be paralell it means that their lines never intersect
The only way for this to be possible is if the lines have the same slope.
This means that the answer is -3
