Answer:All balls have same velocity
Explanation:
Ball A
horizontal velocity
vertical velocity
let h be the height of building
Vertical velocity acquired by Ball A
Velocity just before hitting ground=
Ball B
launched with velocity u at angle of 45 above horizontal
horizontal velocity will remain same as there is no acceleration in that direction
vertical velocity just before hitting the floor
Final velocity before hitting ground
Ball C
horizontal velocity will remain same as there is no acceleration in that direction
vertical velocity just before hitting the floor
Final velocity before hitting ground
Thus all three balls will have same final velocity.
1) Because you have a lower chance of getting electrocuted, 2) 1.DON'T plug a bunch of stuff into one outlet or extension cord, 2.Make sure all electric cords are tucked away neatly, 3.DON'T ever climb the fence around an electrical substation, 4.DON'T yank an electrical cord from the wall, 5.Keep electrical stuff far away from water, 6.Ask a grown-up for help. 3) <span>Always determine if there is power to a circuit or wire using a voltmeter. Never touch any part of a circuit if you did not verify yourself that the the power is off(disconnected). { Trust but verify :President R. Reagan} Having turned off or disconnected the power assure that it cannot be accidentally turned on again by another person. Your Welcome.</span>
Answer:
Δx = 39.1 m
Explanation:
- Assuming that deceleration keeps constant during the braking process, we can use one of the kinematics equations, as follows:
where vf is the final velocity (0 in our case), v₀ is the initial velocity
(25 m/s), a is the acceleration (-8.0 m/s²), and Δx is the distance
traveled since the brakes are applied.
- Solving (1) for Δx, we have:
