The number of radians (d) that the wheel have turned may be calculated by the equation,
d = (v1)(t) + 0.5 x a x t²
where v1 is the initial velocity, a is the acceleration, and t is time. Substituting the known values
d = (18 rad/s)(3s) + (0.5) x (-2 rad/s²) x (3s)²
The value of d is 63 radians.
Answer: The potential energy of the cars at its maximum at the start and the end of the trip. Potential energy approaches zero when the cars are near the ground at the lowest point on the tracks. The kinetic energy of the cars is zero at the start and the end of the trip because cars aren’t moving. Kinetic energy is at its maximum when the cars are the lowest point on the track after racing down the hill. Yw:)
Explanation:
Simple machine is the answer
Answer:
Explanation:The rate of decrease of velocity is given with respect to displacement. As v approaches zero when s approaches 39, it can be written as
where c=19
when s=8 we have
hence a can be found by the chain rule
From the equation
the s in term of t can be found
Hence it can be seen that if s approaches 39 the t function becomes undefined hence s is never 39m
Your experiment should keep one thing constant and measure the other. So vary the temp and measure the pressure. You will get a set of data that relates pressure with temp.
<span>PV = nRT
So
P and T are directly proportional.
