Question

a bus accelerates uniformly from 36 km per hour to 54 km per hour in 10 seconds calculate acceleration​

Answer 1

Answer:

0.5m/s²

Step-by-step explanation:

u = 10m/s

v = 15m/s

t = 10sec

a = v-u/t

= 15-10/10

= 5/10 = 0.5 m/s²

Answer 2

Answer:

Given :-

A train accelerates from 36 km per hour to 54 km per hour in 10 second.

To Find :-

1) acceleration

2) the distance traveled by car​

Solution :-

We know that

1 km/h = 5/18 m/s

36 km/h = 36 × 5/18 = 10 m/s

54 km/h = 54 × 5/18 = 15 m/s

Now

①

We know that

a = (v - u)/t

a = (15 - 10)/10

a = 5/10

a = 0.5 m/s²
