Apickup truck is carrying a toolbox, but the rear gate of the truck is missing, so the box will slide out if it is set moving. the coefficients of kinetic and static friction between the box and the bed of the truck are 0.250 and 0.500, respectively. starting from rest, what is the shortest time this truck could accelerate uniformly to 36.0m/s (≈ 80.5mph ) without causing the box to slide?

Two forces produce equal torques on a door about the door hinge. the first force is applied at the midpoint of the door; the second force is applied at the doorknob. both forces are applied perpendicular to the door. which force has a greater magnitude?

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
