A baseball player applies a force of 200N onto a baseball. Determine the time that baseball player exerts on the baseball if an
2 answers:
Answer:
Time, t = 0.25 seconds
Explanation:
Given that,
Force applied by a baseball player, F = 200 N
We need to find the time that baseball player exerts on the baseball if an impulse of 50 Ns is exerted on the baseball. The impulse exerted on the baseball is given by :
t is time taken
So, the time for which the baseball player exerts on the baseball is 0.25 seconds.

Answer:
9.6J+88.2J=97.8J
Explanation:
Here the velocity of the seagull is given,mass is given and its height.
We have to find its mechanical energy my friend.
Mechanical energy=kinetic energy + potential energy.
First we will find kinetic energy.
For calculating kinetic energy we need mass and velocity,which are given here.
So, Ek=
So by substituting the values we get 9.6J.
Now we find the potential energy which is mgh.
By substituting the values we get 88.2J.
Then we add both of those and get 97.8J

Answer:
Explanation:
Torque, is given by
where F is force and r is perpendicular distance
where
is the angle of inclination
Torque, can also be found by
where I is moment of inertia and a is angular acceleration
Therefore, Fr=Ia and F=mg where m is mass and g is acceleration due to gravity
Making a the subject, and already I is given as
hence
Taking g as 9.81, is given as 37 and L is 1.2
