M/s2 is the SI of an acceleration.
a couple of things that are necessary to measure this :
- use the timing resources to measure the duty cycle
- performing a computationally intensive division operation
Answer:
15.45 m/s
Explanation:
F = 1.2 x 10^3 N, Fk = 615 N, u = 0, s = 25 m
Let the speed after traveling 25 m is v.
mass = F / g = 1200 / 9.8 = 122.45 kg
Net force, Fnet = 1.2 x 1000 - 615 = 1200 - 615 = 585 N
acceleration = Fnet / mass = 585 / 122.45 = 4.78 m/s^2
Use third equation of motion
v^2 = u^2 + 2 a s
v^2 = 0 + 2 x 4.78 x 25 = 238.88
v = 15.45 m/s
The Stratosphere contains the highest concentration of the ozone, this is because the ozone is located here. The Thermosphere has the highest average air temperature also seen as the hot layer, and the Mesosphere is the lowest average sir temperature.
In your question where as ask the man lift various loads with the same lever and the distance of the applied force from the fulcrum is 2m and the distance from the fulcorm to load is 0.5m.So the following are the answers to your questions:
a.mechanical advantage of the lever is 1
b..<span>ideal mechanical advantage of the lever is 4</span>
c.4
