A fisherman is fishing from a bridge and is using a "30.0-N test line." In other words, the line will sustain a maximum force of 30.0 N without breaking. What is the weight of the heaviest fish that can be pulled up vertically, when the line is reeled in (a) at constant speed and (b) with an acceleration whose magnitude is 2.16 m/s2?
A 64.3 kg skydiver jumps out of an airplane with a parachute. She decides not to pull the ripcord until she reaches terminal velocity. If the resistive force proportionality constant is 2.35 kg/s, what is themagnitude of the velocity when she decides to pull the cord? (Assume the drag force is proportionalto the speed.)
A heavy box containing four laptops worth 700,000 pesos is beingdelivered. From the delivery van, it slides down on a rough ramp angled at 30 degrees with respect to the ground. The coefficient of kinetic friction between the box and the ramp is µk = 0.300. If each laptop has a mass of 2kg, what is magnitude of acceleration of the box?
