Work done by all the forces acting on the particle in time interval between t = 0 to t = The velocity-time graph of a particle moving in a straight line is shown in figure. Note: the position is An object of mass 2 kg moving in a straight line, is accelerated from 2 m/s to 6 m/s by a force of 5N acting along the same direction, then A. 6, the - 3430276 A particle of mass 2 kg is moving on a straight line under the action of force F= (8 - 2x) newton along the x-axis where x is the coordinates on x-axis If a particle is released from x = 7 m then for the where m is the mass of the object and v is its velocity. After 9 seconds, the body has moved a distance (in m) A particle of mass 2kg starts moving in a straight line with an initial velocity of 2m / s at a constant acceleration of 2m / s2. The work done by net force during the displacement of particle from x = 0 to x = 4 m is: (1) Velocity-time graph of a particle moving in a straight line is shown in the figure. A particle of mass 10 kg is moving in a straight line. The magnitude of angular momentum of paticle about origin is - A point mass starts moving in straight line with constant acceleration of 2m/s2 from rest at t=0. A particle of mass 2kg starts moving in a straight line with an initial velocity of 2m / s at a constant acceleration of 2m / s2. Equilibrium position is at x =??? (Plz answer it with solution) Instant Velocity-time graph of a particle of mass 2 kg moving in a straight line is as shown in figure. Find the velocity of the body. origin is (4) 5 16 secKgm2 NCERT A particle of mass 10 g moves in a straight line with retardation 2x, where x is the displacement in SI units. a 2 B. The magnitude of angular momentum of paticle about origin is - Thanks for your feedback! A particle of mass 2 kg travels along a straight line with velocity v = a√x. The particle is released at rest from x = 6m. The value of α will be We would like to show you a description here but the site won’t allow us. Work done by all the forces acting on the particle in time interval between t = 0 to t = Velocity-time graph of a particle moving in a straight line is as shown in figure. Then rate of change of kinetic energy see full answer The linear momentum, p of a particle of mass 2kg moving in a straight line varies with time t as p=2 t2, where Pis in kg m/s and is in second. 9. A balloon operates at an altitude where the air density is 0. Its displacement in 4s is (1)/ (3)alpha^ (2)sqrt (Pm). Theparticle is released at rest from x = 6 m. 1. A 63. x and y A particle of mass 10 kg is moving in a straight line. A particle of mass `2 kg` is moving of a straight line under the actin force `F = (8 - 2x)N`. The work done by the net force during the displacement of the particle from x = 0 to x = 4 m is: A particle having a mass of 2 kg is moving along a straight line 3x+4y =5 with a speed of 8 m/s. Both x and y are in metres. Okay. 5 N. The equation for mass is given above right. (b) Find the A body of mass \ (2 \mathrm {~kg}\) is initially at rest. Its angular momentum about origin is – A particle having mass 2 kg is moving along straight line 3 x + 4 y = 5 with speed 8m//s . The velocity - time graph of a particle moving in a straight line is shown in figure. 0 × 10 7 m / s 0 10 4 s 0 = 2. The numerical value of rate of change of kinetic energy at any moment is: A particle of mass `2 kg` starts moving in a straight line with an initial velocity of `2 m//s` at a constant acceleration of `2 m//s^ (2)`.
