Kinetic energy i’m not 100% but like 85% sure
Answer:
Increase
Explanation:
If the mass of the earth increase, with no change in radius, one's weight would also increase considerably.
The reason for this is that, the gravitational force of attraction between the two bodies will increase.
- The gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
- So, increasing the mass of the earth will increase the gravitational force on one's body and hence, an increase in weight.
A reference point is important in determining motion because in order to say that something is moving, you need to have something stationary to compare it to.
Solution1:
0.25 min = 15 secs
a = (v - ) / t
v = 0 (stops to rest), t = 15
⇒ a = -/15
x = t + a
⇒ 10.5 = * 15 + * * 225
10.5 = * 15 -
10.5 = * 7.5
= 1.4 (m/s)
⇒ a = - (m/s^2)
Solution2:
