An antelope moving with constant acceleration covers the distance between two points 70.0 m apart in 6.00 s. Its speed as it passes the second point is 15.0 m/s. What are(a) its speed at the first point and (b) its acceleration

(a) The speed at first point is 8.33m/s.

(b) The acceleration of the antelope is 1.11m/s².

Explanation:

We have, from the kinematics equations, that:

Solving for the acceleration in the second equation, we have:

Then, equating the two equations, we obtain:

So, the speed at the first point is 8.33m/s (a).

Next, we use the first equation to compute the acceleration:

In words, the acceleration of the antelope is 1.11m/s² (b).
