Explanation:
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
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
