an antelope moving with constant acceleration covers the distance between two points 70.0m apart in 7.00 s.Its speed as it passes the second points is 15.0m/s.

Question

a.What is its speed at the fist poin?
b.What is ita acceleration?

Answer 1

the average speed is 10.0 m/s
... 70.0 m / 7.00 s

1st point speed is 5.00 m/s
... 10 = (15 + 5) / 2

acceleration is (10.0 m/s / 7.00 s)
