. Graph shows the acceleration of a 3 kg particle as an applied force moves it from rest along x-axis
The total work done by the force on the particle by the time the particle reaches x = 6 m, is equal to
A. 20 J
B. 60 J
C. 30 J
D. 40 J
Best Answer
Ans: B
Sol: Acceleration as shown in the graph can be converted into force by multiplying with m = 3 kg. Therefore, area under the curve (F – x curve) is
