Q1PhysicsUnit 4: Work, Energy and Power
A force acts on a 3g3 g particle in such a way that position of the particle as a function of time is given by x=3t−\boldsymbol{x}=\mathbf{3} \boldsymbol{t}- 4t2+t3,4 t^{2}+t^{3}, where xx is in metre and tt is in sec. The work done during the first 4s4 s is
Q2PhysicsUnit 4: Work, Energy and Power
Assertion A load when lifted vertically up requires greater effort than to roll the same load up the ramp. Reason The work done in lifting the load vertically up is less.
Q3PhysicsUnit 4: Work, Energy and Power
A single conservative force F(x)F(x) acts on a 1.0−kg1.0-k g particle that moves along the x-axis. The potential energy U(x)U(x) is given⁡by⁡U(x)=20+(x−2)2\operatorname{given} \operatorname{by} U(x)=20+(x-2)^{2} where xx is in meters. At x=5.0m,\boldsymbol{x}=\mathbf{5 . 0} \mathrm{m}, the particle has a kinetic energy of 20 J.What is the mechanical energy of the system?
