Answer: This is due to the Magnus Effect
Explanation: "Which is the force exerted on a rapidly spinning cylinder or sphere moving through air or another fluid in a direction at an angle to the axis of spin. This force is responsible for the swerving of balls when hit or thrown with spin."

Determine the distance at which the lighting struck
First, we need to determine the speed at which the lighting struck because the peed of sound varies with temperature.
At about 28C, the speed of sound is 346m/s
So, we have the following:
Distance is calculated as thus:
Divide by 1000 to get distance equivalent in kilometers
---- Approximated
Answer:
h = 12.6 cm
Explanation:
given,
ground reaction = 788 N
time of force application = 0.9 s
BW = 670 N
Net force = 788 - 670
= 118 N
impulse = F x t
I = 118 x 0.9
I = 107.1 N s
impulse is equal to change in momentum
v = 1.57 m/s
v is the initial velocity before jump
now, height of center of mass
using equation of motion
v² = u² - 2 g h
h = 0.1257 m
h = 12.6 cm
the height of center of mass is equal to h = 0.126 m or 12.6 cm
Answer:
Position of motorist = 33.8 m
position of police officer = 16.9 m
Explanation:
velocity of motorist, v = 13 m/s
initial velocity of police officer, u = 0
Acceleration of police officer, a = 5 m/s^2
let after time t, the velocity of police officer is equal to the velocity of motorist.
v = u + at
13 = 0 + 5 t
t = 2.6 second
Position of motorist after 2.6 second = v x t = 13 x 2.6 = 33.8 m
Position of police officer after t = 2.6 s
s = ut + 0.5 at^2
s = 0 + 0.5 x 5 x 2.6 x 2.6 = 16.9 m
