A car is driven east for a distance of 88 km, then north for 28 km, then in a direction 30 degrees east of north for 25 km. Determine the magnitude of the displacement (in kilometers) of the car from its starting point.

Question

thanks!

Answer 1

add them as vectors:

displacement=88km E + 28km N + 25cos30 N + 25sin30 E.

add the n, and the e components, and add.
