Answer:
Explanation:
Work is equal to the product of force and distance.
We are solving for the distance, d. We know the force is 596.82 Newtons and the work is 35,674.7 Joules.
- If we convert the units for Joules, the problem will be simpler later.
- 1 Joule is equal to 1 Newton meter.
- The work done by the runner, 35,674.7 J, equals 35,674.7 N*m
Substitute the values into the formula.
We want to solve for the distance, so we must isolate d on one side of the equation.
d is being multiplied by 596.82 Newtons. The inverse of multiplication is division. Divide both sides of the equation by 596.82 N
The Newtons will cancel, hence the prior unit conversion.
Let's round to the nearest hundredth, so the answer is concise. The 4 in the thousandth place tells us to leave the 7 in the hundredth place.
The distance covered during the portion of the race is about <u>59.77 meters.</u>
Each ball :
P = m * m/sec
P = 1.0 * 5
P = 5.0 kg.m/sec
in stationary :
P = 1.0 kg * 0.0
P = 0.0 kg.m/sec
hope this helps!
Answer:
Part a)
Part b)
Explanation:
Mass of the disc is given as
m = 2.00 kg
radius of the disc is given as
r = 7 cm
so moment of inertia of the disc is given as
Now given that torque on the disc is
so here the angular acceleration is given as
Part a)
if disc start from rest and then achieve final speed as 1200 rpm then
so final speed is
now the time taken to reach this speed is given as
Part b)
Number of revolution in the same time is given as
