Answer:
the kinetic energy the bat can give to a ball is 2,025 J.
Explanation:
Given;
mass of the bat, m = 2kg
velocity of the bat, v = 45 m/s
The kinetic energy the bat can give to a ball is calculated as;
Therefore, the kinetic energy the bat can give to a ball is 2,025 J.
Answer:
Explanation:
<u>Vertical Launch Upwards</u>
In a vertical launch upwards, an object is launched vertically up from a height H without taking into consideration any kind of friction with the air.
If vo is the initial speed and g is the acceleration of gravity, the maximum height reached by the object is given by:
The object referred to in the question is thrown from a height H=0 and the maximum height is hm=77.5 m.
(a)
To find the initial speed we solve for vo:
(b)
The maximum time or the time taken by the object to reach its highest point is calculated as follows:
Answer:
464.3 N
Explanation:
Given parameters are:
I = 0.065
L = 0.025 m
R = 0.28 m
= 0 m/s
= 5 m/s
t = 0.1 s
Hence,
We must connect two torque equations to find the answer.
Where
Hence,
Thus, N
