A1.10-kg wrench is acting on a nut trying to turn it. the length of the wrench lies directly to the east of the nut. a force 150.0 n acts on the wrench at a position 15.0 cm from the center of the nut in a direction 30.0° north of east. what is the magnitude of the torque about the center of the nut?

In the middle of the night you are standing a horizontal distance of 14.0 m from the high fence that surrounds the estate of your rich uncle. the top of the fence is 5.00 m above the ground. you have taped an important message to a rock that you want to throw over the fence. the ground is level, and the width of the fence is small enough to be ignored. you throw the rock from a height of 1.60 m above the ground and at an angle of 54.0 degrees above the horizontal. part a part complete what minimum initial speed must the rock have as it leaves your hand to clear the top of the fence? express your answer with the appropriate units. part b for the initial velocity calculated in the previous part, what horizontal distance beyond the fence will the rock land on the ground?
