Answer:
Torque = 1191.68 N-m
Explanation:
Given data
mass m = 76 kg
standingdistance r = 1.6 m
Solution
we get here torque that si express as
torque = force × distance ................1
torque = r × F sin(theta)
and we know that
F = mg .........2
and g = 9.8 m/s²
put here value in equation 1 we get
Torque = 76 × 1.6 × 9.8 × sin(90)
Torque = 1191.68 N-m
Answer:
α= 15.4[rad/s^2], 500 [rev/min]
Explanation:
La aceleración angular constante esta definida por la siguiente ecuación:
Para poder llegar a las 2000 [revoluciones /min] estando en 1500 [rev/min], la cuchilla tuvo que incrementar su numero de revoluciones a 500 [rev/min]. Mientras aceleraba.
Answer:
Question 1 the answer is 5 cm for the one pulley system, I just took the quiz
Question 2 is 10 cm
Explanation:
The rope only needs to move 5 cm for the mass to move from 15 to 20.
For the 2 pulley system the string has to move twice as far making it 10 cm. I took the quiz and got 100%
Answer:
C) The first sled (taller hill but gradual slope).
Explanation:
As we know by Mechanical energy conservation law
initial total potential energy = final kinetic energy
so we know that
so we will have
so from above equation we know that the the final speed is directly depending on the height of the object and it is independent of the slope of the plane
so here correct answer will be
C) The first sled (taller hill but gradual slope).
