Answer:
171 ft
Explanation:
The distance to be calculated is AB
AB = AC + BC
AC; Cos 60 = AC ÷ 135
AC = 135 cos 60 = 67.5 ft
BC; Cos 40 = BC ÷ 135
BC = 135 cos 40 = 103.416 ft
AB = 67.5 + 103.416 = 170.9159998210 ft
Distance between starting point to end point = 171 ft
Answer:
Explanation:
Samantha walks along a horizontal path in the direction shown the curved path is a semi circle with a radius of 2 m while the horizontal part is for me what is the magnitude of displacement
Displacement is given by the straight line distance between P and Q. Displacement will be length of straight line joining P and Q
a semi circle with a radius of 2 m
Length of this straight line=4+diameter
=4+(2*2)
=8 m
