Question

A pet-store supply truck moves at 25.0 m/ north along a highway. Inside, a dog moves at 1.75 m/s at an angle of 35.0 degrees east of north. What is the velocity of the dog relative to the road?

Answer 1

Add the two vectors.

Answer 2

25.1

Answer 3

sin 35 degrees = 0.57
0.57 *1.75 = 1
25 + 1 = 26
