1. A particle moves in a straight line and its displacement, s cm, from a fixed point O, t seconds after passing O, is given by s = 27t - t'. Calculate(a) the acceleration of the particle when it comes instantaneously to rest,(b) the velocity of the particle when it is next ...
A particle moves from a point (2m, 3m, 0) to (3 m, 2m, 0) under the action of force of magnitude 5N acting along the line y= x. The work done by the force on
数学calculus题目a particle moves along the x axis so that at any time t>0 its acceleration is given by a(t)=ln(1+2^t) if the velocity of the particle is 2 at time 1 then velocity of the particle at time t=2 is
To find the work done by the force F=10−2x+3x2 as a particle moves from x=0 to x=5 meters, we will follow these steps: Step 1: Understand the Work Done FormulaThe work done W by a force when moving an object from position x1 to x2 is given by the integral of the force ...
3. A particle moves along the x-axis. At time r=0 the particle passes through the origin with speed 8 m s-' in the positive x-direction. The acceleration of the particle at time t seconds,t≥0 , is (4t3-12t) m s 2 in the positive x-direction.Find(a) the velocity of the pa...
12. A particle moves in a straight line so that its velocity v m s' is given by v = 9-r,where t is the time in seconds, measured from the start of the motion. Find(a) the value of t at which the particle is instantaneously at rest,(b) the value of t and the speed when ...
NAA particle moves in a straight line, so that after t second, the distance x from a fixed point O on the line is given by x=(l-2)^(2)(t-5). Then
A particle moves according to a law of motion s f(t), t20, where t is measured in seconds and s in feet. f(t) = t3-6t2 + 9t (a) Find the velocity at time t. v(t) = b) What is the velocity after 2 s? (c) When is the...
A particle moves along a straight line on y-axis. The distance of the particle from O varies with time and is given by :y=20t−t2. The distance travelled by the particle before it momentarily comes to rest is View Solution The position of a particle along X-axis at time t is give...
