Ahorse canters away from a trainer in a straight line, moving 116m away in 14s. it turns abruptly and gallops halfway back in 4.8s. what's its average velocity for the entire trip and using 'away from trainer' as positive direction? .

The average velocity for the entire trip is 6.30 m/s.

Explanation:

Given that,

Distance

Time

A horse canters away from a trainer in a straight line, moving 116 m away in 14 s.

It turns abruptly and gallops halfway back in 4.8 s

(a). We need to calculate the average velocity

Using formula of average velocity

Put the value into the formula

Hence, The average velocity for the entire trip is 6.30 m/s.

answer: option c.

explanation:

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
