I was wondering if someone could help answering these:
5. Acceleration of a⃗ = 5 m/s2 at 30° and b⃗
= 7 m/s2 at 120° act at a point.
Draw a diagram and find a⃗ − b⃗
6. Calculate the resultant of ?⃗⃗⃗⃗3 - ⃗?⃗⃗⃗2 + ⃗?⃗⃗⃗1 when⃗?⃗⃗⃗1 = 15m/s at 85°, ?⃗⃗⃗⃗2 =
25m/s at 175° and ?⃗⃗⃗⃗3 = 12m/s at 235°.
Thanks
