### Example Question #31 : College Physics

The bases on a baseball field are 90 feet apart.

A players hits a home run and gets around the bases in 20 seconds what is the players total speed?

**Possible Answers:**

**Correct answer:**

### Example Question #1 : Motion Diagrams

The bases on a baseball field are apart in a perfect square.

A player hits a home run and goes around all 4 bases. What is the total distance he travelled?

**Possible Answers:**

**Correct answer:**

There is 90 feet between each base and distance does not depend on direction. Distance is scaler therefore, the batter travels 360 feet.

### Example Question #1 : Motion Diagrams

The bases on a baseball field are 90 feet apart.

A players hits a home run and gets around the bases in 20 seconds what is the players total velocity?

**Possible Answers:**

**Correct answer:**

Displacement is a vector. Magnitude and direction matter.

### Example Question #4 : Motion Diagrams

The bases on a baseball field are apart.

A player hits a home run and runs around all four bases. What is his total displacement?

**Possible Answers:**

**Correct answer:**

Displacement is a vector. Therefore, magnitude and direction matters and because direction matters the total displacement is 0 feet.

### Example Question #5 : Motion Diagrams

A ball is dropped and it hits the floor is . How high was the ball dropped from?

**Possible Answers:**

**Correct answer:**

We are dealing with motion in one plane and the initial velocity is zero. We must use the following kinematics equation to plug in known values and solve:

### Example Question #31 : Mechanics

There are between the bases on a baseball field and they make a square.

Jim hits a double and reaches second base in . What is his velocity?

**Possible Answers:**

**Correct answer:**

Velocity is a vector so direction matters. Therefore this creates a right triangle with the two isosceles side having a velocity of . Therefore, the hypotenuse is when you perform Pythagorean theorem.
