A = distance traveled by steve in north direction by train = 30 miles
B = distance traveled by steve in east direction by train = 25 miles
R = resultant displacement of the steve relative to starting position
using pythagorean theorem
R = √(A² + B²)
inserting the values
R = √(30² + 25²)
R = 39.05 miles
direction : tan⁻¹(B/A) = tan⁻¹(25/30) = 39.8 deg east of north
If the box is a distance 1.81 m from the rear of the truck when the truck starts,<span> ... Force of Friction = mu_s * Normal Force( </span>M<span> * G) ... The </span>box starts<span> moving! ... Now that the </span>box<span> is moving, the bed of the </span>truck<span> pulls at it with 17.4 ... out how </span>long<span> it will take the </span>box<span> to reach the back of the </span>truck<span>. ... T^2 = 2 * </span>1.81<span> / .64</span>
The answer would be A, since at that position the Earth is fully/partially being engulfed in a shadow cast by the moon from the sun’s rays.
Hope this helps!
