It is b i had that qustion
They will both hit the ground at the same time due to gravity.
that means they took the same time to travel the distance to the ground
however, the ball traveled farther
speed=distance (or displacement) divided by time
so the greater the distance, the greater the speed
the ball traveled faster in the same time so it traveled faster
answer is ball
VHF Channel 16 must always be monitored. It is the calling and distress channel. This is where the operator might hear a MAYDAY call. This is also where the operator can issue a MAYDAY. Improper misuse of the channel can result to penalties.
Answer:
The spring constant of the spring is 205.42 N/m.
Explanation:
Springs have their own natural "spring constants" that define how stiff they are. The letter k is used for the spring constant, and it has the units N/m.
k = -F/x
The period of a spring-mass system is proportional to the square root of the mass and inversely proportional to the square root of the spring constant.
Given:
mass of object in SHM = m = 0.30 kg
Time period of the spring mass system = 0.24s
Spring constant = k ?
Finding 'k' using Time period 'T':
We know that
Answer:
No she cannot.
Explanation:
Let 
be the horizontal component of the ball velocity when it's kicked, assume no air resistance, this is a constant. Also let 
be the vertical component of the ball velocity, which is affected by gravity after it's kicked.
The time it takes to travel 95m accross the field is
or 
t is also the time it takes to travel up, and the fall down to the ground, which ultimately stops the motion. So the vertical displacement after time t is 0
where g = -9.8m/s2 in the opposite direction with
Since the total velocity that the goal keeper can give the ball is 30m/s
Let substitute x = 
> 0
We can multiply both sides by x
As 
The solution for this quadratic equation is indefinite
So it's not possible for the goal keeper to do this.
