Does anybody know how to do physics

[From: ] [author: ] [Date: 12-11-19] [Hit: ]
Make a triangle. Solve for the length of the long side of the triangle.......
Tammy leaves the office, drives 33 km due
north, then turns onto a second highway and
continues in a direction of 32

north of east
for 89 km.
What is her total displacement from the
office?

-
d² = x² + y²
d² = (33+89sin32)² + (89cos32)²
d² = 33² + 2*33*89sin32+89²sin²32+89²cos²32 = 12122.7
d = 110.1 km

Tammy is 110.1 km straight line distance from the office.

Displacement is a vector quantity that
refers to "how far out of place an
object is"; it is the object's overall
change in position. Just pull a line from the start position to the finish position. And then you have a triangle. Measure the lenght of the line with law of sines calculation (see the wikipedia for law of sines).

Use vectors. And trigonometry.

Make a triangle. Solve for the length of the long side of the triangle.
