Well the object will have no Momentum since it is not moving, so a small object that is going 10 mph will have Momentum.
The terminal speed of the marble is 0.588 m/s.
Given:
We know that,
F = mg ......(1)
where,
F = force
m = mass
g = acceleration due to gravity
Also,
v = F/k ......(2)
where,
v = terminal speed
k = proportionality constant
Substituting the value of F from equation (1) in equation (2)
v = mg/k .......(3)
Given,
m = 30 g = 0.030 kg
k = 0.500 kg/s
g = 9.8 m/s²
To find,
v =?
Put the values in equation (3)
v = mg/k
v = 0.03(9.8)/ 0.500
= 0.294/0.500
= 0.588 m/s

Answer:
Explanation:
I = V/R = 120 V/ 50 Ω = 2.4 A
P = VI = 120(2.4) = 288 W = 288 J/s
288 J/s (15 min(60s / min)) = 259,200 J
or the electric company would charge for
288 W / (1000 W/kW)•(15/60) hr = 0.072 kW•hr
At $0.20 / kW•hr, that would be under 1½ cents
5ft is two times the 10ft
The amount of potential energy the block contains is 2,822.4 Joules
<u>Given the following data:</u>
- Height of platform = 24 meters.
We know that the acceleration due to gravity (g) of an object on planet Earth is equal to 9.8
.
To determine the amount of potential energy the block contains:
Mathematically, potential energy (P.E) is given by the formula;

Where:
- g is the acceleration due to gravity.
- h is the height of an object.
Substituting the parameters into the formula, we have;

Potential energy (P.E) = 2,822.4 Joules
