Question

The labeled graphs below represent the upward trajectories of 4 bodies, two sliding upwards on frictionless inclines and two in free flight. Note that all 4 bodies reach the same maximum height (9 meters) after traveling from the same initial elevation (0 m).

• The initial speed of N is  _______________ that of Q.
• The time of travel of Q is _______________ that of N
• The initial speed of R is  _______________ that of Q.
• The time of travel of P is _______________ that of R
• The time of travel of Q is _______________  that of R.
• The initial speed of P is  _______________ that of R.

The options are: greater than, less than, or equal to.

Explanation / Answer

Considering all the graph of 4 bodies travels the maximum elevation in same time then we can say about the speed comparison. If we assume that all 4 body in the are traveling with the same speed then we can compare about the time.

In this question neither of the case is given. Therefore, assuming that they travel in the same time then

Answers-

a-The initial speed of N is less than that of Q because the slope at its initial position of N is less than that of Q

b-The time of travel of Q is equal to that of N.

c-The initial speed of R is greater than that of Q because of slope.

d-The time of travel of P is equal to that of R.

e-The time of travel of Q is equal to that of R.

f-The initial speed of P is less than that of R because the slope of P is less than R.
