On a distant planet, golf is just as popular as it is on earth. Agolfer tees off and drives the ball 3.10 times as far as he would have on earth, given the same initial velocities on both planets.The ball is launched at a speed of 41.8 m/s at an angle of 34 °above the horizontal. When the ball lands, it is at the same levelas the tee. On the distant planet, what is (a) the maximum height
A hill that has a 25.7% grade is one that rises 25.7 m vertically for every 100.0 m of distance in the horizontal direction. At what angle is such a hill inclined above the horizontal?
A 20.0-kg uniform plank is supported by the floor at one end and by a vertical rope at the other, find the magnitude of the force that the floor exerts on the plank
Two long parallel wires are separated by 4.0mm. The current flowing in one of the wires is twice that in the other wire. If the magnitude of the force on a2.0-m length of one of the wires is7.2µN, what are the values of the two currents? (Enter your ..
Find the minimum volume of concrete (y = 23.6 kN/m3) needed to keep the gate (1 m wide) in a closed position; l = 2 m. Note the hinge at the bottom of the gate. Explain briefly.
Assume the ball leaves Sarah's hand a distance 1.5 meters above the ground, reaches a maximum height of 15.0 m above the ground, and takes 2.692 s to get directly over Julie's head. What is the speed of the ball when it leaves Sarah's hand? m/s 6)..
A house has a floor area of 120 m2 and an outside wall that has an area of 31 m2. The earth's magnetic field here has a horizontal component of 2.60 10-5 T that points due north and a vertical component of 5.00 10-5 T that points straight down, to..
