Average speed = distance travelled / time used
Answer:
I can explain it using the law of force
or Newton's law of motion
Answer:
(a) 1, average velocity = -65.6 m/s
2, average velocity = -64.8 m/s
3, average velocity = -64.16 m/s
(b) The instantaneous velocity is -96 m/s
Explanation:
(a)
Average velocity is given by;

(1)

(2)

(3)

b. y = 235 - 16t²
The instantaneous velocity is given by;
v = dy /dt
dy / dt = -32t
when t = 3 s
v = -32(3)
v = -96 m/s
Answer:
530.5 Hz
Explanation:
Given :
C=0.75 micro
L=120 mH
Reactance capacitor can be determined by
=
where c =capacitor
= 
Reactance inductor can be determined by

As they are in series so ,

On solving these value we get

As we know that
f =
=
530.5 Hz
