In the figure the variation of components of acceleration of a particle of mass 1 kg is shown w.r.t. time. The initial velocity of the particle is 
m/s. The total work done by the resultant force on the particle in time interval from t = 0 to t = 4 seconds is:
Text Solution
Verified by ExpertsThe correct answer is:
B
From given graphs:
a x = 
t and a y = 
⇒ v x = 
t 2 + C
At t = 0: v x = – 3 ⇒ C = – 3
∴ v x = 
t 2 – 3
⇒ dx = 
....
Similarly; dy = 
...
As dw = 
= 
∴ 
∴ W = 10 J
