Please answer this physics question im desperate!! 20 POINTS AND BRAINLIEST!!

Answer 1

Answer:

Hope this helps......

The answer is 5, the magnitude of the acceleration will be in the direction in which the object is moving as it has positive accleleration.

Explanation:

Initial Velocity, u = 10m/s

Final Velocity, v = 20m/s

Time, t = 2s

Acceleration, a = v-u/t

$= acceleration \: = \frac{v - u}{t} \\ = \frac{20 - 10}{2} \\ = \frac{10}{2} \\ = 5$

Please mark as brainliest and follow me.

Answer 2

Answer:

5.0 m/s^2

Explanation:

In the given problem,

u=initial velocity=10.0 m/s

v=final velocity=20.0 m/s

t=time to reach from initial to final velocity=2.00 s

Now using the formula,

acceleration=a=(v-u)/t

                         =(20.0-10.0)/2.00 m/s^2

                          =10.0/2.00 m/s^2

                       =5.0 m/s^2

Note that: s^2 means second square
