An athlete commences a sprint with an acceleration of 5.35 m/s2. Her mass is 53 kg. Calculate the net external force on her. Neglect any frictional force. Select one: A. 265.8 N B. 297.3 N C. 273.0 N D. 256.3 N E. 283.6 N
According to Newton's second law
The net force on any body is equal to its mass multiplied by its acceleration.
In the question, the mass of athlete = 53 kg
Acceleration of athlete= 5.35 m/s2
Net force = 53 kg* 5.35 m/s2 = 283.6 N
Option E is the answer.
An athlete commences a sprint with an acceleration of 5.35 m/s2. Her mass is 53 kg....
