In the movie Speed, a bus already moving faster than 55 mph will explode if the bus’ speed falls below 55 mph. Let say that the
kompoz [17]

Answer:

The bus moved after our girl Sandy passed out = S = 905.04 m

Explanation:

At  t = 0 sec              Vi = 80mph = 35.76 m/s

    t = 30 sec             Vf = 55mph = 24.58 m/s

According to the first equation of motion

                   <u>Vf = Vi + at</u>

        24.587 = 35.76 + a(30)

        a  =  - 0.373 m/s2 (negative sign shows deceleration)

 Now for distance travelled in 30 sec we have

second equation of motion

                <u>  S=Vit+1/2at2</u>

        S = 35.76 x 30 + 1/2 x -0.373 x 30 x 30

         S = 905.04 m

A wheelbarrow full of bricks is lifted to the top of a wall. If the mass of the loaded wheelbarrow is 3000.0 g and the height of
Rina8888 [55]

Answer:

the Gravitational potential energy is 13.23 J

Explanation:

The computation of the GPE is shown below:

GPE stands for Gravitational potential energy

The following formula should be used for the same

= mass × gravity × height

= 3000 g × 9.8m/sec^2 × 0.45 m

= 13.23 J

Hence, the Gravitational potential energy is 13.23 J

We simply applied the above formula so that we can easily determine the GPE
