Acceleration means going faster
Answer:
<h3>The answer is 500 kg</h3>
Explanation:
The mass of the object can be found by using the formula
![m = \frac{2KE}{ {v}^{2} } \\](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B2KE%7D%7B%20%7Bv%7D%5E%7B2%7D%20%7D%20%20%5C%5C%20)
v is the velocity
KE is the kinetic energy
From the question we have
![m = \frac{2 \times 100000}{ {20}^{2} } = \frac{200000 }{400} = \frac{2000}{4} \\](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B2%20%5Ctimes%20100000%7D%7B%20%20%7B20%7D%5E%7B2%7D%20%20%7D%20%20%3D%20%20%5Cfrac%7B200000%20%7D%7B400%7D%20%3D%20%20%20%5Cfrac%7B2000%7D%7B4%7D%20%20%5C%5C%20)
We have the final answer as
<h3>500 kg</h3>

Answer:
uniform acceleration
Explanation:
The definition for uniform acceleration is:
if an object travels in a straight line and its velocity increases or decreases by equal amounts in equal intervals of time, then the acceleration is said to be uniform.

Answer:
Neptune is approximately 41 times as far from the sun as Venus
Explanation:
Estimate = distance of Neptune from the sun ÷ distance of Venus from the sun = 4.5×10^9 ÷ 1.18×10^8 = 40.9 (approximately 41)
