Answer:2t
Explanation:
Given
Jason throwing watermelon at speed v and it spend t time in air
time to reach max height

0=v-gt'

and time to reach bottom is also t'
t=2t'

For guy throws his watermelon at speed 2v
So total time in air will be


t''=2t
Answer:
Direct current
Explanation:
The current that is supplied by electric cells and batteries.Electons flows in one direction and does not change directions.
Here We can use principle of angular momentum conservation
Here as we know boy + projected mass system has no external torque
Since there is no torque so we can say the angular momentum is conserved

now we know that
m = 2 kg
v = 2.5 m/s
L = 0.35 m
I = 4.5 kg-m^2
now plug in all values in above equation

![1.75 = [4.5 + 0.245]\omega](https://tex.z-dn.net/?f=1.75%20%3D%20%5B4.5%20%2B%200.245%5D%5Comega)


so the final angular speed will be 0.37 rad/s
They go in the boxes in this order:

4.hypothesis
5.control
6.kilogram
1.49 MPH (Miles Per Hour)
