Question

10 kilogram Brahman ki ek vastu ko gati man karne ke liye kisi vyakti dwara avashyak Shakti ki ganana kijiye taki uske gati ko 5 second mein 10 metre second se badhakar 20ms kiya ja sake

Answer 1

Answer : 20 N

Explanation:

first we have given the final velocity and initial velocity of block so we can find out acceleration

final velocity V = 20m/s

initial velocity U= 10 m/s

time = 5 sec

acceleration = (V - U) / t = (20 - 10)/5 = 2 m/s^ 2

now we are supposed to find force so force is

F = ma

F = 10kg × 2m/s^2

20 N answer
