Question

Holaaa!!!!!
plz answer to above 8th question with explaination.​

Answer 1

Answer:Your answer is (a)

Explanation:

F=10kgwt

We know that

1kgwt= 9.8N

.:. F=10×9.8N

t= 2sec

u=0

v=10m/s

Now, from equation of motion

v=u+at

10=0+a×2

10=2a

.:. a=5m/s

Now, we know that

F=ma

10×9.8= m×5

.:. m= 19.6 kg**
