Unit 7 Day 12 Practice: Finding R and Theta from Rx and Ry

A nuclear submarine approaches the surface of the ocean at 25.0 km/h and at an angle 17.3 degrees with the surface as shown in the picture. What is the horizontal (Rx) component of its velocity to the nearest tenth?

A nuclear submarine approaches the surface of the ocean at 25.0 km/h and at an angle of 17.3 degrees with the surface as shown in the picture. What is the vertical (Ry) component of its velocity to the nearest tenth?

Vectors A and B are at right angles. Find the magnitude of the resultant rounded to the nearest whole number.

A=592

B=195

Vectors A and B are at right angles. Find the direction (angle from Vector A) of the resultant rounded to the nearest tenth.

A=592

B=195

Vectors A and B are at right angles. Find the magnitude of the resultant rounded to the nearest whole number.
