Question

a car increases its speed from 20 km per hour to 30 km per hour in 10 second It acceleration is
​

Answer 1

Answer:

accelaration is 0.278m/s2

Explanation:

Answer 2

Answer:

Given,   initial velocity(u) = 20 km

             final velocity(v) = 30 km

             time(t) = 10 sec

To find, acceleration (a)

We know that, a=(v-u)/t

=> a = (30 - 20)/10

=> a = 10/10

=> a = 1 km/ sec

=> a = 1000 m/ sec
