A car and driver weighing 7130 N passes a sign stating...?

Physics
1 answer:
IgorLugansk [536]3 years ago
4 0

Answer:

321 280 J

Explanation:

Work done =  force * distance

The distance is 32 m

The force can be calculated using the second law of motion

F = ma = (7130 N ÷ 9.8 m/s²) * 13.8 m/s² = 10 040 N

Work done =  force * distance

                   = 10 040 N * 32 m

                   = 321 280 J

A trunk rotation is a common dyamic flexibility assessment ture or false
Ilia_Sergeevich [38]

True. It would be false if the statement was "trunk rotation is the most common <em>static</em> flexibility assessment."


So, you're answer should be "true". Hope that helped!

A block rests on a ?at plate that executes vertical simple harmonic motion with a period of 0.58s.
SVETLANKA909090 [29]

Answer:

maximum amplitude  = 0.08 m

Explanation:

Given that

Time period T= 0.58 s

acceleration of gravity g= 9.8 m/s²

We know that time period of simple harmonic motion given as

T = 2π/ω

0.58 = 2π/ω

ω = 10.83rad/s

ω=angular frequency

Lets take amplitude = A

The maximum acceleration given as

a= ω² A

The maximum acceleration should be equal to g ,then block does not separate

a= ω² A

9.8 =  10.83² A

A = 0.08m

maximum amplitude  = 0.08 m

Weekend A<br> Assignment<br> Differentiate between forced and damped oscillation
4vir4ik [10]

Answer:

A damped oscillation means an oscillation that fades away with time while Forced oscillations occur when an oscillating system is driven by a periodic force that is external to the oscillating system.

Explanation:

Damping is the reduction in amplitude (energy loss from the system) due to overcomings of external forces like friction or air resistance and other resistive forces. ... When a body oscillates by being influenced by an external periodic force, it is called forced oscillation.
