A900-kg giraffe runs across a field at a rate of 50 km/hr. what is the magnitude of its momentum? 18 km/hr

Contrast the force of gravity between these pairs of objects a 1 kg mass and a 2 kg mass that are 1 m apart and two 2 kg masses that are 1 m apart

True or false graphs must include scales that increase by the same amount

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?
