ANSWER:
a)Angle = 79°
b)Resultant vector = 10.2m/s
a)Use the pythagoras trigonometry ratios to obtain the angle..,
Vertical(opposite) = 10
Horizontal(adjacent) = 2
tan theta = 10/2...,where theta is representing the angle.
;theta = 79°
b) Resultant vector(R)...we use the pythagoras to calculate it,
Where our resultant vector is the hypothenus...,
R^2 = 10^2 + 2^2
R^2 = 104
Hence,
;Resultant vector = square root of 104
= 10.2 m/s
