Q. A particle moves along the x x -axis such that at any time t0 t \geq 0 its position is x(t) x(t) , its velocity is v(t) v(t) , and its acceleration is a(t) a(t) . You are given:\newlinex(0)=4 and v(0)=10 x(0)=4 \text { and } v(0)=10 \newlineWhich of the following expression gives the velocity of the particle when t=10 t=10 ?\newline10+100x(t)dt 10+\int_{10}^{0} x(t) d t \newline10+010a(t)dt 10+\int_{0}^{10} a(t) d t \newline10+100a(t)dt 10+\int_{10}^{0} a(t) d t \newline10+010x(t)dt 10+\int_{0}^{10} x(t) d t
  1. Relationship between velocity and acceleration: To find the velocity of the particle at t=10t=10, we need to use the relationship between velocity and acceleration. The velocity at any time tt can be found by taking the initial velocity and adding the integral of the acceleration from the initial time to time tt.
  2. Initial velocity and integral of acceleration: We are given the initial velocity v(0)=10v(0)=10. To find the velocity at t=10t=10, we need to add the integral of the acceleration from time 00 to time 1010. This is represented by the expression v(t)=v(0)+0ta(t)dtv(t) = v(0) + \int_{0}^{t} a(t) \, dt.
  3. Expression for velocity at t=10t=10: The correct expression that represents the velocity of the particle at t=10t=10 is therefore v(10)=10+010a(t)dtv(10) = 10 + \int_{0}^{10} a(t) \, dt. This corresponds to the second option: 10+010a(t)dt10 + \int_{0}^{10} a(t) \, dt.
