Question

A car travells at 10m per sec to 15m per sec in 5 min calculate rate of change of velocity or acceleration​

Answer 1

Answer:

0 m/s

Step-by-step explanation:

from first equation of motion

V=U+AT

15 =10+a×5

a= 10+5/15

a= 0 m/s

Answer 2

To solve any problems in physics first we should write the given data

So now,

Initial speed =10m/s,

Acceleration =5metre per second square

Distance=30m

Now by applying the third equation of motion we get

V^2=u^2 +2as

V=( 100 + 2×5×30)^1\2

V=20
