Answer:
u = 13.67 m/s
Explanation:
given,
window height = 2 m
window is 7.5 m off the ground on its path up
total distance from the ground to pass the window = 2 + 7.5 = 9.5 m
time taken to go past the window = 1.30 s
using equation of motion



u = 13.67 m/s
hence, the initial velocity of the ball is equal to 13.67 m/s
The appropriate response is hydrogen ions. It entirely, the core of a hydrogen particle isolated from its going with an electron. The hydrogen core is comprised of a molecule conveying a unit positive electric charge, called a proton.
