You throw a football straight up. Air resistance can be neglected. (a) When the football is 4.00 m above where it left your hand

Oksana_A [137]

Answer:

The speed of the football when it lift your hand is 8.86 m/s.

Explanation:

Given that,

Final speed of the football, v = 0.5 m/s

Height above the ground, s = 4 m

We need to find the speed of the football when it left your hand. The ball will move under the action of gravity. Using third equation of motion as:

$v^2-u^2=2gs\\\\u^2=v^2-2gs\\\\u^2=(0.5)^2-2\times (-9.8)\times 4\\\\u=8.86\ m/s$

So, the speed of the football when it lift your hand is 8.86 m/s. Hence, this is the required solution.

"What is the mass in kg of a 3920N piano?" Which formula would this question use? F=ma or W=mg?

AVprozaik [17]

W = mg, because you have the weight of the piano and if you just divide it by g that will give you the mass you need. The piano isn't accelerating right now in a way that you'd need to use F = ma.
