- A wooden block experiences a frictional force, f, as it slides across a table. If a block of the same material with half the height and twice the length were to slide across the table, what would be the frictional force it experienced?A. (1/2)fB. fC. 2fD. 4fm = 8 kg v0 = 6 m/s F = 12 N the box reaches 10 m in 1.4 seconds If you wanted the box to reach a distance of x = 10 m in 0.761 seconds, to what value would you change the force (in N)?A pack of four velociraptors have caught a human running through their jungle. Each raptor grabs one limb and pulls as hard as it can. One raptor exerts a force of 50.0 N at an angle of 20.0 ̊. Another exerts a force of 30.0 N at an angle of 130.0 ̊, while a third exerts a force of 90.0 N at 160.0 ̊. If the meal remains stationary, i.e. the total force is 0, at what angle and with what force is the fourth raptor pulling? Note that force is a vector. Force is measured in units called Newtons which is abbreviated N.
