Question

An object moving with a constant

acceleration changes its velocity from
10ms' to 20 ms' in five seconds. What is the
distance travelled in five seconds ​

Answer 1

Formula = m/s

Step-by-step explanation:

The answer is 10 m / 5 seconds = 2 meters distance

The answer is 20 m / 5 seconds = 4 meters distance

Answer 2

Acceleration:

`{ \tt{a = (v - u)/(t) }} \\ { \tt{a = (20 - 10)/(5) }} \\ { \tt{a = 2 \: m {s}^( - 2) }}`

From third equation:

`{ \bf{ {v}^(2) = {u}^(2) + 2as}} \\ { \tt{s = \frac{ {20}^(2) - {10}^(2) }{2 * 2} }} \\ = { \tt{s = 75 \: m}}`
