Answer:
0.83m/s forward
Explanation:
Velocity is the displacement divided by time.
Velocity =
Displacement is the distance moved in a specific direction;
→ 6meters forward
← 3meters backwards
→ 7 meters forward
Net displacement =7m + 3m = 10m forward
So;
Velocity = = 0.83m/s forward
2.0y i think this is guess but if it right then thats good
The denser one will be the heavier one.
Answer:
μk = 0.26885
Explanation:
Conceptual analysis
We apply Newton's second law:
∑Fx = m*a (Formula 1)
∑F : algebraic sum of the forces in Newton (N)
m : mass in kilograms (kg)
a : acceleration in meters over second square (m/s²)
Data:
a= -0.9 m/s²,
g = 9.81 m/s² : acceleration due to gravity
W= 75 N : Block weight
W= m*g
m = W/g = 75/9.8= 7.65 kg : Block mass
Friction force : Ff
Ff= μk*N
μk: coefficient of kinetic friction
N : Normal force (N)
Problem development
We apply the formula (1)
∑Fy = m*ay , ay=0
N-W-25 = 0
N = 75
+25
N= 100N
∑Fx = m*ax
20-Ff= m*ax
20-μk*100
= 7.65*(-0.90 )
20+7.65*(0.90) = μk*100
μk = ( 20+7.65*(0.90)) / (100)
μk = 0.26885
Answer:
The word "hurricane" is widely known and recognized, but its etymology is lesser-known. Named for Mayan God The English word "hurricane" comes from the Taino (the indigenous people of the Caribbean and Florida) word "Huricán," who was the Carib Indian god of evil. Their Huricán was derived from the Mayan god of wind, storm, and fire, "Huracán."
