Specific gravity.

Elongable power, ultimate.

Elongated, ultimate.

Emphasis at 100% elongation.

Compression group, 22 hrs

Elongable group.

Teardrop power. Fragile power.

43。Throw three identical balls, all with the same initial velocity, juggling the clown to walk a tightrope. The first ball is thrown horizontally, the second is thrown at a level above a certain angle, and.

Third, throw at an angle below some air resistance, described.

The movement of the three balls and compare the speed of the balls as they reach the ground.

The velocity of the rubber ball in kilograms is determined at point A and the kinetic energy of J at point B is determined below.

In one. b Kinetic energy of the ball. The velocity of the ball is in B.

c。The total power done is from A to B

One. The center of gravity under the force.

b Work done. Lost due mechanical energy to friction.

c。The normal force of the work done.

and 46 blocks of inclination. A skier mass kg pulls up the slope by a cable driven by a motor. How much work is needed.

The skier pulls m, with a maximum slope of 35° (assumed frictionless), at a constant speed of meters and seconds.

47。Acrobats on skis start from a standstill on a frictionless track meters above the ground, and fly above the horizontal angle and at a height of meters above the track. Ignore air resistance.

What is the speed of the skier when leaving thetrack?

What is the maximum height reached.

48。Starting from a standstill, down a frictionless ramp from the ground to a kilogram of luggage slides meters. suitcase, then slide along the floor for an extra meter before stopping. Determine the following:

One. The speed of the suitcase is the slope at the bottom.

b。The floor of the trunk.

c coefficient of dynamic friction. due to friction.

49 changes in mechanical energy. The light horizontal spring spring has a spring constant of 105 Nm . A kilogram block compresses one end of the spring, compressing the spring meter.

After the block is released, the block moves meters to the right and only then rests. What is the coefficient of dynamic friction between the horizontal surface and the block? 25。

The spring force constant is Newton-meters. The potential energy stored in the spring is shown as follows:

Centimeters when the spring is stretched.

From the balance b. Centimeters when the spring is compressed.

From the balance c. When it is zero, the stretch of the spring.

43, A juggling clown stands on a taut rope and runs out 3 identical balls, all with the same initial velocity, the first ball is thrown horizontally, the second is slightly upward, and the third is slightly downward, regardless of air resistance, describes the trajectory of the 3 balls, and compares the speed at which they land.

Translation: 1. The weight of a person doing pull-ups is n, ignoring the weight of **.

In the initial centimeter of the elevator, each arm exerts an upward force of 355 n in the torso. If you start moving upwards from a standstill, what is the speed of a person at this point? 2。

The kilogram pole vault runs in meters and seconds above the vault. If the pole vaulter is high the level of the athlete component3. The force of the n box clothes that are pulled to the slope of the meter 115 n is represented along the theramp point.

If the coefficient of dynamic friction between the box and the slope is, the kinetic energy of the thebox is calculated. 4 variations. Tarzan and Jane, whose total mass is kilograms, begin when a meter long vine on the grapes is at an angle with the horizontal plane, their swing.

**Tarzan and Jane's Energy as separate quantities) 5. The spring constant of the vertical spring on the block is Newton meters, pushing downward, compressing the spring release, and the spring and traveling vertically upwards. How high does it go beyond the release point?

Thank you. <> begging.
