Question

which would require greater force accelerating a 10g mass at 5m/s^2 or a 20g mass at 2m/s^2​

Answer 1

Answer:

10 gm mass

Explanation:

case1:m  

1

​

=10g=0.01kg;

a  

1

​

=5ms  

−2

 

now,

F  

1

​

=m  

1

​

a  

1

​

=0.01×5

F  

1

​

=0.05N

case2:m  

2

​

=20g=0.02kg

a  

2

​

=2ms  

−2

 

so,

F  

2

​

=m  

2

​

a  

2

​

=0.02×2

or F  

2

​

=0.04 N

We find that F1>F2, hence more force is required to accelerate a 10 g mass at 5ms  

−2

, than accelerating a 20 g mass at 2ms  

−2

Answer 2

Answer:

20g mass at 2m/s^2
