Question

a bus increases its speed form 20km/h to 50km/h in 10seconds calculate its acceleration​

Answer 1

Explanation:

given:

a bus increases its speed form 20km/h to 50km/h in 10seconds calculate its acceleration

to find :

calculate its acceleration

solution :

• Initial velocity = u = 20km/hr = 20 x 5/18 = 5.56
• m/ s

• Final velocity = v= 50 km/hr = 50 x 5/18 = 13.89

• m/s

• Time = t = 10 sec

• Acceleration = a

• a = (v-u) / t

• = (13.89- 5.56) / 10

• = 0.833 m/s²
