Maria took a walk to the store. during maria's trip, when was her displacement equal to zero ?

Displacement is different from distance in a sense that distance takes into account all the points moved by an object while displacement is the shortest way between the initial and final position. In this case, the displacement of Maria would be equal to zero if she return back home.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
