Question

In a golf tournament, if we designate the hole as the origin, and the putter (like a bat) is at -5.0 m at time 0 s, the velocity-time graph for the golf ball will be

• A. a straight line inclined to the time axis
• B. a straight line parallel to the time axis
• C. a concave curve
• D. a convex curve

Answer 1

The correct option is B a straight line parallel to the time axis

Displacement = change in position

From the given data, $s=t$

$v=\frac{s_2-s_1}{t_2-t_1}$

$=\frac{t_2-t_1}{t_2-t_1}=1m/s$
