Question

An object moving with the speed of 35m/s
has a kinetic energy of
9800J
What is the

mass of
the object ​

Answer 1

Step-by-step explanation:

kinetic energy=1/2mv²

1/2mv²=K.E

1/2m(35)²=9800

1/2m=8

m=16 kg

Answer 2

Answer:

mass of object = m = 16 kg

Step-by-step explanation:

We have , v = 35 m/s , K.E. = 9800 J

We know that , K.E. = 1/2mv²

∴ m = 2 × K.E. / v²

∴ m = 2 × 9800 / (35)²

∴ m = 19600 / 1225

∴ m = 16 kg
