Answer:
60.18 N
Explanation:
Given that:
The force applied on the sled = 100 N
Suppose, the angle between the sled rope and the ground = 53°
The horizontal force which acts in the horizontal direction can be expressed as:
But if the angle between the sled rope is parallel to the ground. Then, we use an angle on a straight line which is = 180°
= 100 × -1
= -100 N
I would say option D, it depends on the size of the star
The first one it's very windy today and will rain later.
Answer:
x ’= 368.61 m, y ’= 258.11 m
Explanation:
To solve this problem we must find the projections of the point on the new vectors of the rotated system θ = 35º
x’= R cos 35
y’= R sin 35
The modulus vector can be found using the Pythagorean theorem
R² = x² + y²
R = 450 m
we calculate
x ’= 450 cos 35
x ’= 368.61 m
y ’= 450 sin 35
y ’= 258.11 m
