Here are two vectors: veca = (4.0m) hati - (3.0m)hatj and vecb = (6.0m)hati + (8.0m)hatj. What are (a) the magnitude and (b) the angle (relative to hati) of veca? What are (c ) the magnitude and (d) the angle of vecb ? What are(e) the magnitude and(f) the angle veca + vecb, of (g) teh magnitude and (h) the angle of veca =- vecb, and (i) the magnitude and (i) the angle of veca - vecband veca - vecb ? |
