Answer:motion
Explanation:
kinetic energy of an object that it possess due to its motion.
Answer:
An object changes position if it moves relative to a reference point. The change in position is determined by the distance and direction of an object's change in position from the starting point (displacement). Direction • Direction is the line, or path along which something is moving, pointing, or aiming.
Explanation:
Answer:
The magnitude of the boy's displacement is 24.698 paces which is in the direction of approximately 58.24° North of East
Explanation:
The given parameters are;
The distance West the boy on a treasure hunt walks = 12 paces
The distance North the boy on a treasure hunt then walks = 21 paces
The distance East the boy on a treasure hunt then walks = 25 paces
Writing the displacement in vector format, gives;
d = -12·i + 21·j + 25·i
Which gives
d = 13·i + 21·j
The magnitude of the boy's resultant displacement is given as follows;
![\left | \mathbf{d} \right | = \sqrt{d_x^2 + d_y^2}](https://tex.z-dn.net/?f=%5Cleft%20%7C%20%5Cmathbf%7Bd%7D%20%5Cright%20%7C%20%3D%20%5Csqrt%7Bd_x%5E2%20%2B%20d_y%5E2%7D)
Where;
![d_x = 13, \ d_y = 21](https://tex.z-dn.net/?f=d_x%20%3D%2013%2C%20%5C%20d_y%20%3D%2021)
![\left | \mathbf{d} \right | = \sqrt{13^2 + 21^2} = \sqrt{610} \approx 24.698 \ paces](https://tex.z-dn.net/?f=%5Cleft%20%7C%20%5Cmathbf%7Bd%7D%20%5Cright%20%7C%20%3D%20%5Csqrt%7B13%5E2%20%2B%2021%5E2%7D%20%3D%20%5Csqrt%7B610%7D%20%20%5Capprox%2024.698%20%5C%20paces)
The magnitude of the boy's displacement is 24.698 paces
The direction of the displacement is tan⁻¹(21/13) ≈ 58.24° North of East.
