Answer:
Gold metal is a noble metal,i.e.,it is a non-reactive metal. As such,it does not form compounds with any other elements naturally. So it is found in its native or pure state in nature.
Answer:
Constant speed is your answer.
Explanation:
Answer:
a) S = 24.4 m/s
b) angle from the +y direction = 28.7°
Explanation:
1) Data
Vy = 21.4 m/s = constant
Vy,o = 0
Ax = 0.301 m/s²
t = 38.9 s
a) V = ?
b) angle=?
2) Formulas
i) Vy = constant = Vy,o
ii) Vx = Vx,o + Ax t = 0 + Ax t = Ax t
3) Solutions
a) speed
t = 38.9 s and Vx,o = 0.301 m/s² ⇒ Vx = 0.301 m/s² × 38.9s = 11.7 m/s
V² = Vx² + Vy² = (11.7 m/s)² + (21.4m/s)² = 594.85 m² / s²
⇒ V = 24.39 m/s
b) angle measured from the +y direction
tan (angle) = Vx/Vy = 11.7 m/s / 21.4 m/s = 0.5467
angle = arctan(0.5467) ≈ 28.7°
An object in motion tends to stay in motion an oject at rest stays at rest.
The first law states that “objects at rest and objects in motion remain in motion in a straight line unless acted upon by an unbalanced force”. Keeping the ice smooth will make sure there is not friction, friction would slow the puck down
