Question
The kinetic energy of the particle at $t=20 \mathrm{~s}$ with respect to the ground is(A) $5 \times 10^{3} \mathrm{~J}$(B) $6 \times 10^{3} \mathrm{~J}$(C) $8 \times 10^{3} \mathrm{~J}$(D) $7 \times 10^{3} \mathrm{~J}$
Step 1
The kinetic energy (K.E) of an object is given by the formula: \[ K.E = \frac{1}{2} m v^2 \] where \(m\) is the mass of the object and \(v\) is its velocity. Show more…
