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$$ m s ^ { - 1 }...
A particle starts from rest at a point X and moves in a straight line until, 60 seconds later, it reaches a point Y. At time ts after leaving X, the acceleration o f the particle is$$ 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 ...
aThe weekend is very great. 周末是非常伟大的。[translate] aA particle will stay at rest or continue at a constant velocity, unless acted upon by an external unbalanced force。 微粒将停留休息或继续在恒定的速度,除非由外在失衡的力量行动。[translate]...
A particle of mass4mwhich is at rest explodes into massesm,m&2m. Two of the fragments of masses m and2mare found to move with equal speeds v each in opposite directions. The total mechanical energy released in the process of explosion is :- ...
At time t=0, a particle, P, is at rest at the point (2,0). At time t seconds, its acc
A particle starts from rest at the point (2,0) and move along the x-axis with a constant positive acceleration for time t≥q 0. Which of the following could be the graph of the distance s(t) of the particle from the origin as a function of time t? ( ) A. B. C. D. ...
A particle moves along the x-axis with velocity v(t) = (21t^2-t) \; m/s. Find the particle's position s(t) assuming that s(2) = 6. A particle, initially at rest, moves along the x-axis such that its acceleration at time give...
Answer to: An object, initially at rest, is giving a constant acceleration of 0.5. Calculate the time it takes to travel 100m. By signing up,...
