A particle, initially at rest, starts moving in a straight line with an acceleration a=6t+4m/s2. The distance covered by it in 3 s is View Solution Starting from origin at t=0, with initial velocity 5ˆjm/s, a
To find the distance traveled by a particle starting from rest and moving with an acceleration of 3m/s2 in the 5th second, we can follow these steps: Step 1: Understand the problemThe particle starts from rest, which means its initial velocity u=0m/s. The acceleration a=3m/s2. We need...

A particle starts from rest at a point X and moves in a straight line until, 60 seconds later, it reaches a point Y. At time ts after leaving X, the acceleration o f the particle is$$ 0 . 7 5 m s ^ { - 2 } f o r 0 ...
The following considerations deal with the theoretical foundations of particle movement in a fluid as long as these are of importance for the problems of sedimentation or air classification analysis. As is well known, these measurement principles are partially based on the fact that it is possible ...
Find the velocity of the particle when the acceleration is zero. View Solution A particle starts moving from rest on a straight line. Its acceleration a verses time t is shown in the figure. The speed of the particle is maximum at the instant View Solution A particle starts from rest ...
A particle originally at rest at the highest point of a smooth vertical circle is slightly displaced. It will leave the circle at a vertical distance h below
A particle of mass 2kg is initially at rest on a rough horizontal plane. A force of magnitude 10N is applied to the particle at $$ 1 5 ^ { \circ } $$ above the horizontal. It is given that 10s after the force is applied, the particle has a speed of 3.5$$ m s ^ { - 1 }...
4 A particle P moves on a straight line, starting from rest at a point O of the line. The time after P starts to move is ts, and the particle moves along the line with constant accelerationms2 until it passes through a point A at time t = 8. After passing through A the velocity...
2.1.4. Moving the particles To keep an orderly flow of particle, the particles are moved using the XSPH variant,(12)dradt=va−ϵ∑bmbρ¯abvabWabrabhwhere ρ¯ab=ρa+ρb/2 and ϵ is a problem-dependent constant, ranging from 0 to 1. It moves a particle at a velocity clos...
