Suppose that an electric current flows in a straight wire. You change the system so that the current flows in the opposite
direction. Predict what changes will occur in the magnetic field, and what will
stay the same.

total distance/total time

(85 + 82)/(5+3)

167/8

20 just over

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

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
