What are the following statements? If there's one that mention a description of current action, or motion, that's your answer.
Answer:
Explanation:
An impulse results in a change of momentum.
The impulse is the product of a force and a distance. This will be represented by the area under the curve
a) W = ½(4.00)(3.00) = 6.00 J
b) W = (11.0 - 4.00)(3.00) = 21.0 J
c) W = ½(17.0 - 11.0)(3.00) = 9.00 J
d) ASSUMING the speed at x = 0 is in the direction of applied force
½(3.00)(v₄²) = ½(3.00)(0.450²) + 6.00
v₄ = 2.05 m/s
½(3.00)(v₁₇²) = ½(3.00)(0.450²) + 6.00 + 21.0 + 9.00
v₁₇ = 4.92 m/s
If the initial speed is NOT in the direction of applied force, the final speed will be slightly less in both cases.
C2 = a2 + b2
29^2 = a^2 + 20^2
841 = a^2 + 400
441 = a^2
a = 21
Answer: charge Q = 40Coulombs
Explanation: The current in a circuit is the quantity of charge that flows through it per second.
Here the 2amp current is same as the amount of charge in coulomb that flows through the terminal in ONE second.
So, if 2 coulomb of charge flows in 1sec then in 20 secs we will have
Q(charge) = 2*20 = 40 coulombs
Explanation:
Given that,
Net force = 135.5 N
Mass = 26.7 kg
(a). We need to draw a free body diagram
A force is exerted on a object.
(b). We need to calculate the acceleration
Using formula of acceleration
(c). We need to draw the sketch a position vs. time graph for the object.
Using equation of motion
Put the value into the formula
(d). We need to draw the sketch a velocity vs. time graph for the object.
Using equation of motion
Put the value into the formula
(e). We need to calculate the distance travel in 8.82 s
Using equation of motion
Hence, This is the required solution.
