Question

car starts from rest acquires velocity 15 M per second in 120 seconds find acceleration and distance travelled during this time

Answer 1

Hi Mate Here is Your Answer,

GIVEN :

V= 15m/sec
T= 120 sec.
U=0 m/sec
A=?

How to find acceleration?????
We can simply find it by applying the below written Formula.....

a = (v-u)/t

Now in this formula substitute the given values than solve the equation ;

a= (15-0)/120

a= 15/120 = 5/40 = 1/8 = 0.125......... (Ans.)

● ANS IS 0.125 M/SEC^2

From second law of motion we know

S= Ut+1/2 × a×t^2
Now substitute Values,

S= 0×120+1/2× 1/8 x 120 ×120

S= 1/2×1/8×120×120

S= 1/16×120×120

S= 900

● So the distance is 900m.

HOPE THIS HELPS YOU A LOT......☺♤♤♤♤
