Question

1. A vector is heading northeast making a magnitude of a-50 m/s. The vertical component ay will be? angle of 30° with the positive x-axis ,has an 2. A velocity vector points is acting at 60° North of East. The horizontal component is 20 m. What the is the vector magnitude?

Please rate good dear student if you like my solution

Notes Ans I The Date given vector is as shown- - (North Y La 50m/? X (East) It is given in question, South If we draww perpendiculars from beint p to x& y anis which intersecto at M N respectively. 1 Лом P, 2 м = 30° o op- ontMe triangle law of A vector addition, -) a = a ľ tay i here la l = a = 50m/s² . Sin 30 = ay 2 somis? =)) ay = 25 m/s Answer.

Date Lot Ansa The required velocity vector is making 60 angle with East anis towards north side, which is as shown North/ y-anis) RIM Last ( conist | 20m/s the as required velocity vector (W) is shown op as shown above- The K- Component of relocity is 20m/s. - Voc=20m/s = v costo zu A OMP LM=go => V cos 60° = x =) V = Vo = 20m/5 - home = v= 40m/s) Answer cos60° 1/2
