Question

7. A boy starting from rest travels a distance of 200 m in 10 s. Calculate the magnitude of his
acceleration.
​

Answer 1

Answer:

itz 20m/s .

Explanation:

we know, a =v-u/t

a = acceleration

u is initial velocity

v is final velocity

t stands for time

so, u is 0 ( boy at rest)

v is 200m(final position)

t is 10 s

so,

a = v - u / t

= 200m - 0/ 10s

= 200m/10s

= 20m/s

itz the magnitude of the acceleration .
