Suppose a 0.250-kg ball is thrown at 15.0 m/s to a motionless person standing on ice who catches it with an outstretched arm as shown in the figure.
(a) Calculate the final linear velocity of the person, given his mass is 70.0 kg.
(b) What is his angular velocity if each arm is 5.00 kg? You may treat his arms as uniform rods (each has a length of 0.900 m) and the rest of his body as a uniform cylinder of radius 0.180 m. Hint: Place the arm rods on top of the body cylinder, i.e., ignore the skater\'s head. Neglect the effect of the ball on his center of mass so that his center of mass remains in his geometrical center.
A box with a mass of 8 kg is lifted (without acceleration) through a height of 9 m, in order to place it upon the shelf of the closet.
A 69.00 kg person on skis is going down a hill sloped at 30° from the horizontal. The coefficient of friction between the skis and the snow is 0.20. What would be magnitude of the acceleration.
A 0.65 percent C hypoeutctoid plain carbon steel is slowly cooled from about 950°C to a temperature just slightly above 723°C. calculate the weight percent austenite and weight percent proeutectoid ferrite in this steel. Explain it.
A rock with mass m = 3.70 kg falls from rest in a viscous medium. The rock is acted on by a net constant downward force of F = 19.3 N and by a fluid resistance force.
The small spherical planet called "Glob" has a mass of 6.54×10^18 kg and a radius of 6.29×10^4 m. An astronaut on surface of Glob throws a rock straight up. The rock reaches a maximum height of 2.00×103 m, above the surface of planet, before it falls..
A rocket is launched from the origin with an acceleration of 20.0 m/s2 at an angle of 30.0 degrees above the horizontal. What is the total time of flight

You have a 56.9-mF capacitor initially charged to a potential difference of 10.1 V. You discharge the capacitor through a 4.77-Ω resistor. What is the time constant? After what multiple of the time constant does the potential difference reach 2.47 V.
When high-energy charged particles move through a transparent medium with a speed greater than the speed of light in that medium, Calculate the speed of the electrons in the water. The speed of light in water is 2.25 108 m/s
A basketball player grabbing a rebound jumps 70.80 cm perpendicularly. How much total time (ascent and descent) does the player spend (a) in the top 11.2 cm of this jump and (b) in the bottom 11.20 cm? Do your results describe why such players see..
