The longer the lever the longer the power
Answer:
after 6 second it will stop
he travel 36 m to stop
Explanation:
given data
speed = 12 m/s
distance = 100 m
decelerates rate = 2.00 m/s²
so acceleration a = - 2.00 m/s²
to find out
how long does it take to stop and how far does he travel
solution
we will apply here first equation of motion that is
v = u + at ......1
here u is speed 12 and v is 0 because we stop finally
put here all value in equation 1
0 = 12 + (-2) t
t = 6 s
so after 6 second it will stop
and
for distance we apply equation of motion
v²-u² = 2×a×s ..........2
here v is 0 u is 12 and a is -2 and find distance s
put all value in equation 2
0-12² = 2×(-2)×s
s = 36 m
so he travel 36 m to stop
Answer: The pattern of the battery is wrong, the bulb is broken , the wires of the circuit is broken , the switch is not closed .
The rate of the inlet pipe is 1/18 of the pool volume per hour while the drain pipe is 1/36 volume per hour.
The net rate meaning if the two pipes work simultaneously is 1/18 – 1/36 = 1/36 of the pool volume per hour.The equation to know the t for filling 1/3 of the remaining volume of the pool is 1/36 * t = 1/3Solving for t is through cross multiplication. Thus it gives us t = 12.
