A56 kg sprinter, starting from rest, runs 49 m in 7.0 s at constant acceleration. what is the sprinter's power output at 2.0 s, 4.0 s, and 6.0 s

The sprinter's power output at 2.0  is 2,744 J/s.

The sprinter's power output at 4.0 s is 1,372 J/s.

The sprinter's power output at 6.0 s is 914.67 J/s.

The given parameters;

The acceleration of the sprinter is calculated as follows;

s = u + ¹/₂at²

49 = 0 + (7² x 0.5)a

49 = 24.5a

a = 2 m/s²

The force exerted by the sprinter is calculated as follows;

F = ma

F = 56 x 2

F = 112 N

The sprinter's power output at 2.0 s;

The sprinter's power output at 4.0 s;

The sprinter's power output at 6.0 s;
