SUMMARY

The discussion focuses on calculating the speed and acceleration of an antelope moving with constant acceleration over a distance of 70.0 meters in 7.0 seconds, reaching a final speed of 15.0 m/s at the second point. To find the initial speed (v0) and acceleration (a), participants suggest using the kinematic equation: x = x0 + v0*t + 0.5*a*t^2. The need for clarity on relevant equations is emphasized, with participants seeking guidance on applying these formulas effectively.

PREREQUISITES
  • Understanding of kinematic equations for constant acceleration
  • Familiarity with basic physics concepts such as speed, distance, and time
  • Ability to manipulate algebraic equations
  • Knowledge of initial and final velocity definitions
NEXT STEPS
  • Study the kinematic equations for constant acceleration in detail
  • Practice solving problems involving initial and final velocities
  • Learn how to derive acceleration from distance and time
  • Explore graphical representations of motion under constant acceleration
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in mastering kinematic equations and constant acceleration problems.

Homework Statement



an antelope moving with constant acceleration covers the distance between two points 70.0 m apart in 7.0 s. Its speed as it passes the second point in 15.0 m/s .

a) what is its speed at the first point?
b)what is the acceleration?

Homework Equations



what do you mean by relevant equations??
please give me a little more idea.

The Attempt at a Solution



well, honestly I am advancing to what my teacher teach on us. because she is absent in the last meeting. :( i figure that X sub 0 is 70.0 m and I am stuck at that. i can't figured out how to determine the symbol that i will use.

i think i can use the formula x = X sub 0 + V sub 0x + 1/2 asubx t^2

Write out all the standard constant acceleration equations.

In part 3, choose one of them, and use it to solve the problem … it will have to include vi vf s and a.
