Which one of the following statements is true?
The displacement x of a particle moving along a straight line at time t is given by x = a0 + a1 t + a2 t2 What is the acceleration of the particle
\(v-\frac{dx}{dt}-a_{1}+2a_{2}t\)
\(∴v-\frac{dv}{dt}-2a_{2}\)
If the displacement of a particle varies with time as \(\sqrt{x}=t+7\), the(a)(b)(c)(d)
\(\sqrt{x}=(t+7)\: or\: x=(t+7)^{2}\)
\(\frac{dx}{dt}=2(t+7),∴velocity\alpha time\)
The area of the acceleration-displacement curve of a body gives
The slope of the velocity time graph for retarded motion is
Which of the following changes when a particle is moving with uniform velocity?
The displacement of a body is zero.The distance covered
A particle has moved from one position to another position
The ratio of the numerical values of the average velocity and average speed of a body is always:
The study of motion, without consideration of its cause is studied in
