Thus, a swinging pendulum has its greatest kinetic energy and least potential energy in the vertical position, in which its speed is greatest and its height least; it has its least kinetic energy and greatest potential energy at the extremities of its swing, in which its speed is zero and its height is greatest.
Answer:
R = 1,746 Ω
Explanation:
The power dissipated in the circuit is
P = V I = V² / R
Let's find the current
R = V² / P
Let's calculate
R = 13²/81
R = 2,096 Ω
This is total resistance
R_total = R + r
R = R_total - r
R = 2,096 -0,350
R = 1,746 Ω
Answer:
a) V1 = -1.49 m/s

I hope it helps you. Thank you
(a) time taken for the car to accelerate from v to 2v = t =
(b) velocity of the car moving at 2t seconds = ΔV = 2at
(a) we know that,
a=
where, is the final velocity
is the initial velocity
a = acceleration
t = time
Time taken to accelerate from V to 2V:
t =
(b) We know that,
a=
where, is the final velocity
is the initial velocity
a = acceleration
t = time
how fast is the car moving at 2t seconds after starting,
we can represent - = ΔV
at time = t= 2t, it becomes
a= = a = ΔV/2t
t= ΔV/2a
ΔV = 2at
<h3>What is acceleration?</h3>
Rate of change of velocity with time, both in terms of speed and direction is known as acceleration.
<h3>What is speed?</h3>
- the rate at which an object's location changes in any direction.
- The distance traveled in relation to the time it took to travel that distance is how speed is defined.
- Since speed simply has a direction and no magnitude, it is a scalar quantity.
