A ball is thrown straight up from the earth surface with an initial velocity 60 m/s. The displacement of a ball at a time, , from an initial point is () and is given by ()=60−32+5. A.1 Determine the velocity and acceleration of a ball at any instant of time .
A.2 Obtain the velocity and acceleration at a time =5 and 10 seconds.
A.3 At what time ball will fall on the earth surface.
A.4 Conclude and comment on the results.
