Calculate the velocity of a baseball that travels 100 m in 5 sec.
r-ruslan [8.4K]

The velocity of the baseball is 20m/s

Velocity can be described as the speed of an object that is moving in a particular direction

The formula for calculating velocity is

velocity= displacement/time

The first step is to write out the parameters given in the question.

time= 5 seconds

displacement= 100m

The velocity can be calculated as follows;

velocity/displacement

= 100/5

= 20

Hence the velocity of the ball is 20m/s

Please see the link below for more information on velocity

-6 to the power of 4, is equivalent to: (-6) ^ 4

So we have to:

-6: It is the base

4: It is the exponent

Answer:

Find the coordinates of the three points on the graph of y = (1/2)x² -2x whose x-values are −2, 0, and 4.
MaRussiya [10]

Answer:

y = 6

y = 0

y = 0

Step-by-step explanation:

y=\frac{1}{2}x² -2x

When, x = -2

y=\frac{1}{2}\times (-2)^2-2\times(-2)\\\Rightarrow y=\frac{1}{2}4+4\\\Rightarrow y=2+4\\\Rightarrow y=6

y = 6

When, x = 0

y=\frac{1}{2}\times (0)^2-2\times(0)\\\Rightarrow y=0+0\\\Rightarrow y=0

y = 0

When, x = 4

y=\frac{1}{2}\times (4)^2-2\times(4)\\\Rightarrow y=\frac{1}{2}16-8\\\Rightarrow y=8-8\\\Rightarrow y=0

y = 0
