Question

study the velocity time graph and calculate a) the acceleration from B to C b) th distance velocity from C to D c) the average velocity from C to D d)the acceleration fromA to B e) the distance covered in region BCFE

Answer 1

Hello ,

here is your answer ,

_____________________


●(a) Acceleration from B to C

$= > \frac{17 - 25}{4 - 3} = - 8 \: m \: {s}^{ - 2}$


● (b) Distance velocity from C to D

$= > \frac{25 - 20}{6 - 4} = \frac{5}{2} = 2.5 \: m \: {s}^{ - 1}$


● (c) Average velocity from C to D

$= > \frac{17 + 0}{2} = 7.5 \: m \: {s}^{ - 1}$

●(d) Acceleration from A to B

$= > \frac{25 - 0}{3 - 0} = 8.3 \: m \: {s}^{ - 2}$

●(e) The distance covered in region BCFE

$= > \frac{1}{2} \times (17 + 25) \times 1 = 21 \: m$
