Incomplete question as the mass of ball is missing.So I assume the mass of ball is 0.35 kg.The complete question is here
A baseball has mass 0.35 kg. (a) If the velocity of a pitched ball has a magnitude of 43.5 m/s and the batted ball’s velocity is 57.5 m/s in the opposite direction, find the magnitude of the change in momentum of the ball and of the impulse applied to it by the bat.Express your answer to three significant figures and include the appropriate units.
Answer:
J=4.90 kg.m/s
Explanation:
First, we take the batted balls velocity as the final velocity and its direction is the positive direction and we take the pitched balls velocity as the initial velocity and so its direction will be negative direction So we have:
We plug our values for m and vi.So we get the initial momentum of ball:
We plug our values for m and vf.So we get the final momentum of ball:
So the change in momentum is:
Δp=p₂ - p₁
Δp=(20.125 kg.m/s) - (15.225 kg.m/s)
Δp=4.90 kg.m/s
We get the impulse applied to the ball by bat as follow
J=Δp
J=4.90 kg.m/s
Answer:
hmax=81ft
Explanation:
Maximum height of the object is the highest vertical position along its trajectory.
The vertical velocity is equal to 0 (Vy = 0)
we isolate th (needed to reach the maximum height hmax)
The formula describing vertical distance is:
So, given y = hmax and t = th, we can join those two equations together:
if we launch a projectile from some initial height h all you need to do is add this initial elevation
Answer:
T= 327.04 N
Explanation:
Initial velocity , u = 0 m/s
Final velocity ,v= 15.4 m/s
m = 584 kg
t= 27.5 s
We know that
v= u + a t
15.4= 0 + 27.5 a
a= 0.56 m/s²
From second law of Newtons
T= m a
T= 584 x 0.56 N
T= 327.04 N
(And don't forget that an object going around a curve at a constant speed is also accelerating.)
I believe there are two reasons:
1). The term is inadequately taught in the American public school system ... along with much of the rest of Science and Math in general.
2). The word became permanently and indelibly corrupted when the automotive industry decided to name the gas pedal the "accelerator".
Answer:
Get turned Into Water.
Explanation:
Combustion of Hydrogen involves combining oxygen and hydrogen essentially so when oxygen and hydrogen combine water is produced, following chemical equation describes this process.
.
Resulting product is two molecules of water.
