A body, starting from rest and moving with a constant acceleration, covers 10 m in the first second. The distance travelled by it in the 2nd second is [ ] a) 19 m b) 10 m c) 20m d) 30 m​

Answer 1

Answer:

c) 20m

velocity initially is =0

final velocity = 0

a=∆v/∆t

a=10-0/1-0

a= 10 m/s^2

velocity after 2 sec = 10×2=20

Answer 2

Option c is correct

20meter
