A particle moves in one dimension from rest under the influence of a force that varies with the distance travelled by the particle as shown in the figure. The kinetic energy of the particle after it has travelled 3 m is : |
A) 2.5 J
B) 6.5 J
C) 4 J
D) 5 J
Correct Answer: B
Solution :
\[\frac{1}{2}m{{V}^{2}}=4+2+0.5=6.5J.\]You need to login to perform this action.
