Question

the mass of a body is 20 kg. it is moving with a speed of 10 m/s . What is its kinetic energy?

Answer 1

Answer:

IF THE SUM OF THE FIRST p TERMS OF AN A.P. IS q AND SUM OF FIRST q TERMS IS p SHOW THAT THE SUM OF FIRST p + q TERMS IS - (p + q).IF THE SUM OF THE FIRST p TERMS OF AN A.P. IS q AND SUM OF FIRST q TERMS IS p SHOW THAT THE SUM OF FIRST p + q TERMS IS - (p + q).IF THE SUM OF THE FIRST p TERMS OF AN A.P. IS q AND SUM OF FIRST q TERMS IS p SHOW THAT THE SUM OF FIRST p + q TERMS IS - (p + q).

Explanation:

Answer 2

Answer:

1000 joules

Explanation:

kinetic energy=½mv²

given:m=20kg

v=10m/s

kinetic energy=½×20×(10)²

=½×20×100

=½×2000

=2000/2

=1000 joules

kinetic energy= 1000 joules
