A truck travels beneath an airplane that is moving 100 km/h at an angle of 49 degrees to the ground.

A) how fast must the truck travel to stay beneath the airplane? Answer in units of km/h

The answer I got was 65.6 km/h, but i just wanted to make sure someone else got the same answer.also there's a part B which i am not sure how to find...

B) What is the magnitude of the verticle component of the velocity of the plane. Answer in units of km/h

• Physics -

yes on a, on b, the vertical component is 100sin49deg
