The press box at a baseball park is 30.0 ft above the ground. A reporter in the press box looks at an angle of 18.0 degrees below the horizontal to see second base. What is the horizontal distance from the press box to second base?
Two dogs pull horizontally on ropes attached to a post; the angle between the ropes is 55.0 degrees. Dog A exerts a force of 270 N and dog B exerts a force of 350 N. Find the magnitude of the resultant force.
Then accelerates out, reaching her previous speed of 65.0 m/s after a distance of 350 m. At this point how far has the Thunderbird fallen behind the Mercedes Benz, which has continued at a constant speed?
The skier is traveling with a speed of 8.00 m/s. How much force must you apply, in newtons, over the 12.0 meter flat stretch?
Three charged particles are placed at the corners of an equilateral triangle of side 1.20 m. The charges are + 7.0 mc,-8.0 mc and -6.0 mc. Calculate the magnitude and direction of the net force on each due to the other two.
What apparent free-fall acceleration is experienced by the managers remaining on the rim assuming that the average mass for each inhabitant is 65.0kg
A sled weighs 100N. it is held in place on a frictionless 20 degree slope by a rope attached to a take at the top; the rope is parallel to the slope. what is the normal force acting on the sled?
When a bullet fires in a gun, the explosion subsides quickly. Suppose the force on the bullet is F(t) = F0 - βt^2 until the force is zero, and then zero thereafter. Assume F0 = 357 N and β = 1.20E+7 N/s2 and the mass of the bullet is 0.0
A ball is held on an incline at the height of 75cm. it is then released so that the ball rolls down the incline. at the bottom of the incline there is a loop where the ball rolls around in. If the loop is 60cm high at its highest point what is th
Suppose the flame on a gas burner stove emits light just like a blackbody. The flame appears blue, emitting most of its light at a wavelength of 475 nanometers. What is the temperature of the flame?
