A shot putter launches a 6.970 kg shot by pushing it along a straight line of length 1.650 m and at an angle of 33.60° from the horizontal, accelerating the shot to the launch speed from its initial speed of 2.500 m/s (which is due to the athlete's preliminary motion). The shot leaves the hand at a height of 2.110 m and at an angle of 33.60°, and it lands at a horizontal distance of 14.00 m. What is the magnitude of the athlete's average force on the shot during the acceleration phase?
make Use of a 9.81 m/s^2 for the magnitude of the acceleration due to gravity.
ow does this change in amplitude affect the wave's frequency.
The spring constant for the tendon is the same for both groups, 32 {rm {N}/{mm}} . What is the difference in maximum stored energy between sprinters and nonathletes.
The coefficient of static friction
Calculate the smallest coefficient of static friction necessary for mass A to remain stationary.
In deep space two spheres each of radius 5.00 m are connected by a 3.00 x 10^2 m nonconducting cord. If a uniformly distributed charge of 35.0 mC resides on the surface of each sphere, calculate the tension in the cord.
Tension is maintained in a string. The observed wave speed is 25 m/s when the suspended mass is 3.0 kg. (a) What is the mass per unit length of the string? (b) What is the wave speed when the suspended mass is 1.7 kg?
The initial angle of the ball’s motion off the tee is 29.0° above the horizontal. If the tee level is 17.0 m above the level of the fairway, explain how far east of the tee does the ball hit the fairway?
A car is traveling along a straight road at a velocity of +34.0 m/s when its engine cuts out. For the next ten seconds, the car slows down, and its average acceleration is a1.
A resistor is in the shape of a cube, with each side of resistance R . Find the equivalent resistance between any two of its adjacent corners.
The calorimeter is constructed of a material that has a specific heat of 0.10 cal/ g. ^{circ}C. When equilibrium is reached, what will be the final temperature.
Light with a wavelength of 4.5 x10-5 cm passes through a single slit and falls on a screen 100 cm away. If the slit is 0.015 cm wide, what is the distance from the center of pattern to first dark band.
