If a car is traveling forward at 15 M/S, how fast will be going in 1.2 seconds if the acceleration is 10 M/s2?

Answers

Answer:

Vf=27m/s

Explanation:

Vf=Vi+at

Lets substitute the known variables into the equation:

Vf=15+10×1.2

Vf=27m/s

So itll be going 27metres per second

Roller coasters accelerates from initial speed of 6.0 M/S2 final speed of 70 M/S over four seconds. What is the acceleration?

Answers

Answer:

[tex]a=16\ m/s^2[/tex]

Explanation:

Motion With Constant Acceleration

It's a type of motion in which the velocity of an object changes uniformly in time.

The formula to calculate the change of velocities is:

[tex]v_f=v_o+at[/tex]

Where:

a   = acceleration

vo = initial speed

vf  = final speed

t    = time

The roller coaster moves from vo=6 m/s to vf=70 m/s in t=4 seconds. To calculate the acceleration, solve for a:

[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]

[tex]\displaystyle a=\frac{70-6}{4}=\frac{64}{4}[/tex]

[tex]\boxed{a=16\ m/s^2}[/tex]

a 950 N skydiver jumps from an altitude of 3000 m. What is the total work performed on the skydiver?

Answers

Answer:

2850000J

Explanation:

Given parameters:

Weight of diver = 950N

Altitude  = 3000N

Unknown:

Total work done by the sky diver = ?

Solution:

To solve this problem, we use the expression:

        Work done  = Weight x height

Now insert the parameters:

        Work done  = 950 x 3000  = 2850000J

Significant resources are allocated to mitigate the risk. Our company is committed to ensuring that employees, visitors and contractors are kept as safe as possible whilst at any premises owned or under the control of the organisation. With this in mind, all staff should familiarise themselves with the locations of the fire alarms, fire call points, fire exits, fire assembly areas and fire tally boards. On discovering a fire, you should operate the nearest alarm, evacuate the building as described below and report the nature and location of the fire to the companys fire warden. On hearing the fire alarm, you should:Quickly and calmly evacuate to the nearest assembly area.Where there is anyone with mobility impairments, utilise the evacuation chair (if trained in its use) or escort them to a temporary refuge point i.e. stairwell or corridors protected by 30 minute fire doors and remain with them if appropriate.Members of staff: If you are near the tally board AND the visitor sign-in sheet, you must pick up both, check the rooms shown on the tally board as you exit and close all doors behind you. Note the location of anyone with mobility impairment who has been escorted to a temporary refuge point. If the tally board/visitor sign-in sheet has already been collected, go straight to the assembly area.If you have collected the tally board and visitor sign-in sheet and checked the rooms as you left the building, you must report with the tally board and visitor sign-in sheet to the companys Fire Warden without delay, informing him/her of the location of any one with mobility impairments waiting in a safe area.If you have looked for a tally board that you know is missing from its usual location, then report this to the companys Fire Warden.Fire wardens should assume their designated duties. Ensure all staff members and visitors/contractors are accounted for. DO NOT attempt to fight a fire unless you have been trained to and it is safe to do so.DO NOT leave the site unless instructed to do so.Why do you think the visitor sign-in sheet needs to be taken?- it is part of the fire evacuation procedure.- the visitor sign in sheet helps account for evacuated visitors accurately.- the visitors sign in sheet can help to locate people.- it assists the fire warden to evacuate people more quickly After a tropical storm in a certain state, news reports indicated that 19 percent of households in the state lost power during the storm.
