Answer:
Explanation:
The centripetal acceleration requirement must equal gravity at the top of the circle
mg = mv²/R
v = √Rg
v = √(1.0(9.8))
v = 3.1304951...
v = 3.1 m/s
<span>Од сила е еднаква на масата * aceleration
Ние го имаме тоа сила = 5N, маса = 0.6kg a =?
5 = 0,6 * a.
Затоа a = 5 / 0,6
a = 8.33m / s²

Answer:
2. A force of 50 N is applied to the object for a distance of 2.0 m. Assume that object（the mass of the object is 3kg）
was at rest at the beginning, what speed did it achieved because of the work done on it? (Hint:
Calculate the works performed by the force first.)
I figured that is 8.2m/S，I am just not sure can anyone help me i much appreciate it.
Umm I think that it's called a run off! Because it's running off of a surface into water.
Answer:
Velocity ratio of a lever is 3 means distance travelled by effort is 3 times the distance travelled by the load. Efficiency of the pulley is 60%means 40% of the energy is lost in the machine due to the friction
