A dragster and driver together have mass 943.8 kg. The dragster, starting from rest, attains a speed of 25.3 m/s in 0.57 s .
Find the average acceleration of the dragster during this time interval.
Avg. Acceleration = Change in velocity/ time taken
= (25.3 - 0)/.57
= 44.38 m/s^2
Force = Mass X Acceleration
= 943.8 X 44.38
= 41486.42 Newtons
The mass of driver is 71.4 kg and acceleration of car is 44.38 m/s^2.
Net force exerted by car on driver = mass of driver X acceleration = 3168.73
