u (initail velocity ) = 60km/hr= 16.67 m/s apprx
My Textbook Solutions
v( nal velocity) = 0 m/s
a= - 0.5 m/s^2
Using kiunematic equation,
v^2 - u^2 = 2as
0 - 16.67^2 = 2(-0.5)S
s= 277.77 m

Q: A ball of mass m, attached to a mass-less string, is released from rest with the cord taut. Find the equation of motion that
describes the motion of the ball in terms of the coordinate 0. The initial position is such that the string is horizontal and
upon leaving the ball, the ball swings like a pendulum. Please note that the string is in-extensible and that the ball is small
