Question

0.2 if initial velocity of a body is 20 m/s and after 10 second its final velocity become 50 m/s then
calculate acceleration of the body.



​

Answer 1

Answer:

we know that the formula for acceleration is 7x+3².so your answer will be 2

Answer 2

$acceleration = \frac{v2 - v1}{t}$

$acceleration = \frac{50 - 20}{10}$

$acceleration = \frac{30}{10} = 3 \frac{m}{ {s}^{2} } = 3m {s}^{ - 2}$
