A student planner is a planner given to students in order to create organization and better communication. With these planners being a part of the classroom experience, students are more likely to keep track of their assignments, set personal goals, and enhance communication between teachers, students and parents.

Determine the angle between the directions of vector a = 3.00i 1.00j and vector b = 1.00i 3.00j .

Katena32 [7]

The angle between the two vectors is 126° 52' 11".

The given parameters;

vector A = 3.00i + 1.00j

vector B = 1.00i + 3.00j

The angle between the two vectors is calculated as follows;

$cos \theta = \frac{A.B}{|A|.|B|}$

The dot product of vectors A and B is calculated as;

A.B = ( 3i + 1j ) . ( 1i +3j )

= ( 3 × 1 ) + ( 1 × 3 )

= 3 + 3

= 6

The magnitude of vectors A and B is calculated as;

|A| = $\sqrt[]{3^2 + 1^2} = \sqrt[]{10} \\$

|B| = $\sqrt[]{1^2 + 3^2} = \sqrt[]{10} \\$

The angle between in two vectors is calculated as;

$Cos \theta = \frac{6}{\sqrt[]{10}\sqrt[]{10} } \\\\Cos \theta = \frac{6}{\ 10 }\\\\Cos \theta = 0.6\\\\\theta = cos^-^1 (0.6)\\\\\theta = 126\\$

Therefore, the angle between the two vectors is 126° 52' 11".

A baseball is thrown with an initial velocity of 45.4 m/s at an angle of 31.2 ∘ .

sveticcg [70]

Answer:

V (initial vertical velocity) = 45.4 sin 31.2 = 23.52 m/s

1/2 m V^2 = m g h conservation of energy

h = V^2 / (2 g) = 23.52^2 / 19.6 = 28.2 m max height

Check:

t = 28.2 / 9.8 = 2.88 sec time to reach max height

h = 23.52 * 2.88 - 1/2 g 2.88^2 = 27.1 m
