Answer:
Range will become 4 times of initial range
Explanation:
Let the velocity of projection is u
And angle at which projectile is projected is 
And acceleration due to gravity is 
So range of projectile is equal to
........eqn 1
Now in second case it is given that velocity of launching is doubled
So new velocity 
So new range will be equal to
.....eqn 2
Now dividing eqn 2 by eqn 1


So if we double the initial launch speed then range will become 4 times
The force acting on his feet.
Average speed = total distance travelled / total time taken
total distance = 3 + 2.5 + 7 + 10 + 2 = 24.5
total time = 120 seconds
therefore 24.5/120 is
0.2m per second.
Answer: B) Uranium
Fossil fuels are natural fuels that were formed from the buried remains of living organisms that lived millions of years ago. Uranium is not a fossil fuel, but it is considered as a nonrenewable fuel.
