Answer:
The potential difference across the source is 30.45 V.
Explanation:
In this setup we have a voltage divider, we were given the voltage difference on one of the resistors, we know that the difference pottential from the source in this case is the sum of the voltage in each individual resistor, so we can use the following equation to solve this problem:
V_resistor5.4 = (V_source)*(R_5.4)/(R_5.4+R_8.3)
V_source = (V_resistor5.4)*(R_5.4+R_8.3)/(R_5.4)
V_source = (12)*(5.4+8.3)/5.4
V_source = (12)*(13.7)/5.4 = 30.45 V
he potential difference across the source is 30.45 V.
Acceleration = (change in speed) / (time for the change)
Cheetah's change in speed = +21 m/s
Acceleration = (21 m/s) / (6.25 s)
Acceleration = (21 / 6.25) (m / s·s)
Acceleration = 3.36 m/s² (about 0.34 of 1 G)
Answer:
diretion and speed will change
Explanation:
Take for example you take a sh*t off a roof and it is fired at 30 degrees it will be pulled to 0 degrees and it will and decrease in speed because of air there will be drag but it will surely land on some one.
(DON'T TAKE ANY OF THIS SERIOUSLY)

Answer:
Initial velocity (u) = 40 m/s
Distance travel in last 5 seconds = 100 m
Explanation:
Given:
Acceleration (a) = 8 m/s²
Final velocity (v) = 0 m/s
Find;
1] Initial velocity before 5 sec
2] Distance travel in last 5 seconds
Computation:
1] Initial velocity before 5 sec
v = u + at
0 = u + (-8)(5)
u - 40 = 0
Initial velocity (u) = 40 m/s
2] Distance travel in last 5 seconds
s = ut + (1/2)(a)(t²)
s = (40)(5) + (1/2)(-8)(5²)
s = 200 - 100
Distance travel in last 5 seconds = 100 m
Same time
