A machine uses a force of 200 newtons to do 20,000 joules of work in 20 seconds. Find the distance the object moved and the power of the machine.
Answers
20,000 joules= 200 newtons * d
divide both sides by 200
100= distance

Answer:
equation gives the position at a specific time for an object with constant acceleration
Explanation:
equation gives the position at specific time for an object having constant acceleration. Constant acceleration is referred as the change of velocity with respect to the time is known as the acceleration, but when the velocity changes occurs at constant rate this rate is termed as the constant acceleration. The constant acceleration can never be zero. The velocity changes but that change occurs in the consistently. The acceleration is affected by the mass.
B. moving with a constant speed
C. slowing down
D. maintaining a constant velocity

"Zero acceleration" means "velocity" that's not changing.
Sadly, it seems that both of these words are almost always
misinterpreted and misunderstood. "Acceleration" does NOT
mean "speeding up", and "velocity" does NOT mean speed.
"Velocity" is the speed AND direction of motion. So, for example,
'30 miles per hour north' and '30 miles per hour west' are the same
speed but different velocities.
"Acceleration" is ANY change in speed OR direction. Consider three
different families in three different cars. One car is speeding up, one is
slowing down, and the third is driving around a curve at a steady speed.
ALL three of the cars are accelerating.

Zero acceleration means velocity that's not changing.
