Answer:
0.4 s
Explanation:
The time that the ball is in the air can be found with the next formula:

where
is the initial velocity of the ball, in this case:

β is the angle: β = 29.0°
And g is the acceleration of gravity: 
Replacing all the values to find t, we have:

Thus, the ball is 0.4s in the air.
The difference is that physical weathering is a process that weathers rock without a chemical reaction or change. Chemical weathering changes the identity of rocks and it involves a chemical reaction or change.
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'.
