Density equals mass × volume
d=m/V
then m=d×V=19.3×2=38.6g
m=38.6g

The distance travelled by the body on last second of its upwards journey is 4.935m
What is projectile motion?
A projectile is an object or particle that is launched toward the surface of the Earth and moves along a curved path only under the influence of gravity.
To solve this question, consider the horizontal distance to be H and
distance traveled by the body in the last second be d


H=510.2m
Now time taken to reach a height of
510.2 m= ![\sqrt[n]{2H/g}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7B2H%2Fg%7D)
=10.2 seconds
Now,



d=4936m
So, the correct answer is '4.936m'.

Answer:
<h2>98 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
PE = 5 × 9.8 × 2
We have the final answer as
<h3>98 J</h3>
