Answer: 3kg: 14.7 6kg: 29.4 9kg: 44.1
Explanation: just did it on Edge
Here's the solution :
Let's find the final velocity :
Initial velocity (u) = 0 (cuz it started from rest)
Final velocity (v) = 8 m/s
Time taken (t) = 10 sec
now, we know that :
Acceleration = 0.8 m/s²
I will answer both versions assuming what you want to know is the distance it travels up from and over the ground. and how long until it reaches space. 540 meters per second up and over. to reach space which is 100km above sea level, it would take about 5400 minutes
B. The electric potential at the given point from the proton is 2.7 x 10¹ volts
<h3>
Electric potential of the proton</h3>
The electric potential of the proton is calculated as follows;
V = kq/r
where;
- k is Coulomb's constant
- q is charge
- r is distance
V = (9 x 10⁹ x 1.6 x 10⁻¹⁹)/(5.3 x 10⁻¹¹)
V = 27.2 volts
V = 2.7 x 10¹ volts
