Newton's second law states that F=ma so that means force =mass×acceleration force and mass
Answer is in the question :)
The gravitational potential energy is calculated by multiplying the mass of the object to the height and the gravitational acceleration which is 9.8 m/s^2. We do as follows:
GPE = mgh
GPE = 4942
4942 = m (9.8)(6.15)
m = 82 kg
Hope this helps.
Gram formula mass means the <span> mass of one moles of the compound
so </span> The mass of 1.0 moles of this compound is <span>48g</span>
<span>so i conclude option 3 is correct
hope it helps</span>
Answer:
A.
B. t = 50 s
Explanation:
A. The vectorial equation of the person who is getting closer to the other person is:
r: position vector
v: speed vector = 6m/s i (if you consider the motion as a horizontal motion)
Then, you replace and obtain:
B. The time is:
d: distance to the observer = 300m
v: speed of the person on the car = 6.00 m/s
