8 0

Answer:

2.0 Hz

Explanation:

2.0 Hz is the most closest to the middle number in between 2.8 and 1.5 Hz. 1.6 Hz would not be suitable as it is too close to 1.5 Hz and 2.7 would also not be suitable as it is too close to 2.8 Hz.

Ben climbs a tree to retrieve a lost football. If he does 2,400 J of work to climb 8 m, how much force is he using?
krok68 [10]
Work = Force * distance.
d = 8 m
W = 2400 J
F = ???

2400 = 8 * F
F = 2400/8
F = 300 N

An object begins with a speed of 20 meters per second and slows down to a speed of 10 meters per second over a time of 5 seconds
Andreyy89

Answer:

V = 6 m/s

Explanation:

Given that,

Initial speed of an object is 20 m/s

Final speed of an object is 10 m/s

Time, t = 5 s

We need to find the average speed of the object during these 5 seconds. Let it is equal to V. Here, time is same. The average speed is given by :

V=\dfrac{x+y}{2}\\\\\text{Putting values}\\\\V=\dfrac{20+10}{5}\\\\V=6\ m/s

So, the average speed of the object is 6 m/s.

An object acted on by a constant force F moves from point 1 to point 2 and back again. The work done by the force F in this roun
aksik [14]

Answer:

F is non-conservative.

If F were conservative no work would be done in moving back to the original point.       F dot S = W     if the net distance is zero the work done is zero for a conservative force
