Answer: 
Step-by-step explanation:
Given: Mass of baseball=0.145 kg
Speed of baseball=40 meters per second
Also it is given that The kinetic energy (in joules) of a moving object can be calculated from the expression
, where 'm' is the mass of the object in kilograms and 'v' is its speed in meters per second.
Thus, the kinetic energy of baseball=

Answer:

Step-by-step explanation:
The formula for distance is:

Where (x₁, y) and (x₂, y₂) are the points.
We are given (-6, 6) and (-3, 3). If we match the value and its corresponding variable, we see that:
- x₁= -6
- y₁ = 6
- x₂ = -3
- y₂ = 3
Substitute the values into the formula.

Solve inside the parentheses.
- -3 --6 = -3+6 = 3
- 3-6 = -3

Solve the exponents.
- (3)²= 3*3= 9
- (-3)²= -3*-3 =9

Add.


Round to the nearest tenth. The 4 in the hundredth place tells us to leave the 2 in the tenth place.

The distance between the two points is apprximately <u>4.2</u>
