Answer

1.negative work

2. kinetic energy and motion of ball

3. ball lost energy

4. kinetic energy

Explanation:

1:when you catch a ball that time their are two forces involved

a. force exerted by ball on your hand

b. Force exerted by you on ball  to stop it. Here the direction of force applied by you on the ball is in opposite direction to the motion of ball. it means direction of applied force and displacement of ball are in opposite direction it means work done by you on baseball is negative a.

2.When we catch a baseball that time we change its kinetic energy, force and its motion. A moving ball has kinetic energy and to stop the ball we have to change kinetic energy of ball. When we catch a baseball the kinetic energy of ball is transferred to our hand. When we catch a ball our hand moves in backward direction with ball because our hand gain energy.

3. Baseball lost energy and this energy is transferred to our hand.

4. Baseball has kinetic energy

An airplane flies 2500 miles east in 245 seconds what is the velocity of the plane?
forsale [732]

Speed = (distance) / (time)

Speed = (

Velocity = speed, and its direction

The velocity of the plane is 10.2 miles per second East.

(about 48 times the speed of sound)

A student has designed a circuit with one battery, two light bulbs, and two switches, pictured to the left. She would like for e
Gnoma [55]

Answer:

The bulb is not powered because the negative end of the battery is not connected to the electric current,making it dysfunctional. The electrons have to flow through the positive and negative ends of the battery in order for it to work.

Hope this helps.

if a torque of 55.0 N/m is required and the largest force that can be exerted by you is 135 N what is th e length of the lever a
Whitepunk [10]

Answer:

r=0.41m

Explanation:

Torque is defined as the cross product between the position vector ( the lever arm vector connecting the origin to the point of force application) and the force vector.

\tau=r\times F

Due to the definition of cross product, the magnitude of the torque is given by:

\tau=rFsin\theta

Where \theta is the angle between the force and lever arm vectors. So, the length of the lever arm (r) is minimun when sin\theta is equal to one, solving for r:

r=\frac{\tau}{F}\\r=\frac{55\frac{N}{m}}{135N}\\r=0.41m
