The change in velocity is 10 mi/h (4.47 m/s)
Explanation:
The change in velocity of the motorcyclist is given by
![\Delta v = v-u](https://tex.z-dn.net/?f=%5CDelta%20v%20%3D%20v-u)
where
v is the final velocity
u is the initial velocity
In this problem, we have
u = 0 (the motorbike starts from rest)
v = 10 mi/h
Therefore, the change in velocity is
![\Delta v = 10 -0 = 10 mi/h](https://tex.z-dn.net/?f=%5CDelta%20v%20%3D%2010%20-0%20%3D%2010%20mi%2Fh)
And keeping in mind that
1 mile = 1609 m
1 h = 3600 s
We can convert it into m/s:
![\Delta v = 10 \frac{mi}{h} \cdot \frac{1609 m/mi}{3600 s/h}=4.47 m/s](https://tex.z-dn.net/?f=%5CDelta%20v%20%3D%2010%20%5Cfrac%7Bmi%7D%7Bh%7D%20%5Ccdot%20%5Cfrac%7B1609%20m%2Fmi%7D%7B3600%20s%2Fh%7D%3D4.47%20m%2Fs)

i just need points rn sorry
Explanation:
The potential energy is defined as Ep=m*g*h where m is the mass of the body, g=9.81 m/s² and h is the height of the body. In our case m=0.01 kg and h=1.5 m. So when we input the values into the equation:
Ep=0.01*9.81*1.5= 0.14715 J.
So the potential energy of a grape is Ep=0.14715 J.
