Answer:
For an object to accelerate, appropriate force must be applied to the object to cause it to change it’s velocity if it’s already in motion. However, to cause it to overcome static friction if it is at rest, and cause it to change it’s velocity
Explanation:
Option B makes the most sense. Option A is something you acquire, it wouldn't really cost anything. Utilities usually do not cost more than housing. Savings are subjective, dependent on the person. So option B.
Hope it helps!
Answer:
Explanation:
given,
wavelength, λ = 50 cm
speed, v = 4 m/s
Amplitude, A = 5 cm
general equation of the wave along x- axis
sign is positive when wave is traveling in negative direction
now,
inserting all the values
Hence, the y-equation of wave is equal to
The cart comes to rest from 1.3 m/s in a matter of 0.30 s, so it undergoes an acceleration <em>a</em> of
<em>a</em> = (0 - 1.3 m/s) / (0.30 s)
<em>a</em> ≈ -4.33 m/s²
This acceleration is applied by a force of -65 N, i.e. a force of 65 N that opposes the cart's motion downhill. So the cart has a mass <em>m</em> such that
-65 N = <em>m</em> (-4.33 m/s²)
<em>m</em> = 15 kg
