Answer:
4117.65 N
Explanation:
Speed of ball, u = 126 km/h = 35 m/s
Mass of ball, m = 160 g = 0.16 kg
Time interval, t = 1.36 ms = 0.00136 s
We can calculate the force as a measure of the momentum of the ball:
F = P/t
Momentum, P, is given as:
P = mv
Therefore:
F = (mv) / t
F = (0.16 * 35) / (0.00136)
F = 4117.65 N
The force imparted to the two glove d hands of the inexperienced catcher is 4117.65 N.
0J
Explanation:
A wall that is acted upon by a force of 20N does not move suggests that no work has been done on the wall.
Work done is the force applied to move in the direction of the applied force.
Work done = force x distance.
Since the distance is 0, the work done on the body too is zero.
Work is only done when forces moves a body through a given distance.

Solve for j and Tj than you have
-j=4Tj
4T=-j/j
4T=-1
T=-1/4
Answer:
Part a)
Part b)
Part c)
Part 4)
angular acceleration will be ZERO
Part 5)
Explanation:
Part a)
Moment of inertia of the system about left end of the rod is given as
So we have
Part b)
If force is applied to the mid point of the rod
so the torque on the rod is given as
now angular acceleration is given as
Part c)
position of center of mass of rod and sphere is given from the center of the sphere as
so moment of inertia about this position is given as
so we have
Part 4)
If force is applied parallel to the length of rod
then we have
so angular acceleration will be ZERO
Part 5)
moment of inertia about right edge of the sphere is given as
so we have
