Science has definitely taken some drastic advancements and made all of us somewhat dependent on these innovations. There are several concepts of science that have made our lives a little bit easier and interesting. Yes, we are talking about those physics motions that we all even apply in our daily lives and have been practically proven like velocity and motion. One such motion that we all know about is rectilinear motion, the motion that well describes the linear motion where the direction of the velocity will remain constant and the path so we know is a straight line. But, that’s just the definition, there is a lot more that we should know about this motion. Try this trivia quiz and see how well you can perform.
1. At zero acceleration if a particle is moving along a straight line. So, what is the velocity of a particle at the position of
x = t4 -20t2 + 42 ?
A. - 42 m/sec
B. + 42 m/sec
C. + 48.68 m/sec
D. - 48.68 m/sec
2. A ball dropped from a wall of height h travels a distance of 50 m in the last two seconds before landing. Explain the height of the wall where the ball dropped?
