WILL GIVE BRAINLIEST PLEASE HELP ACCELERATION QUESTIONSS

Explanation:

Just remember the formula of acceleration is

acceration=

so...

1st one is done...

Initial velocity (u) = 0m/s (It was in rest)

Final velocity (v) = 60m/s

Time (t) = 10s

acceleration (a) = ?

(Remember to always change the units into SI before solving)

Now,

(use the formula)

a = (60-0/10) m/s^2

= 60/ 10 m/s^2

= 6m/s^2

6.

(from 0m/s) so initial velocity (u) =0m/s

(to 40 m/s) so final velocity (v) = 40m/s

time (t) = 4 seconds

acceleration (a) = ?

Now,

a= ( 40-0/4 ) m/s^2

= 40/4 m/s^2

= 10m/s^2

its a 5.5 n

glad that

the rearrangement of particles in a physical change. hope this
