Question

Force required in accelerating a 3 kg mass at 5 m/sq.sec and a 4 kg mass at 4 m/sq.sec, will be:
1 point
zero in both the cases
same in both the cases
greater for 3 kg mass at 5 m/sq.sec
greater for 4 kg mass at 4 m/sq.sec1​

Answer 1

Explanation:

Force F=ma

(1) : F

1

=m

1

a

1

=2×5=10 N

(2) : F

2

=m

2

a

2

=4×2=8 N

So, 2 kg will require greater force.

Answer 2

Answer:

greater for 3 kg mass at 5m/s².
