Question

SOLVE THIS AS FAST AS YOU CAN..

1. A force produces an acceleration of 2 m/s2 when applied on a body of mass 1 kg.

a) Find the magnitude of force.

b) Calculate the acceleration produced by the same force when applied to a body of mass

2 kg.

2. A truck of mass 4 × 107

kg is pulled by a force of 6 × 105 N.

a) Calculate the acceleration.

b) Find its velocity after 10 minutes if initially the truck was at rest.​

Answer 1

Answer:

F=m×a Now, When the some force

F=6m2 is applied on the two bodies

Now, 4m

1

=6m

2

together, Mass =m

1

+m

2

So m

2

=

3

2

m

1

=m

1

+2/3m

1

=5/3m

1

Now, force on second body and force =4m

1

was 6m

2

so, Using,

6m

2

=6×(2/3m

1

)=4m

1

a=F/m

a=

5/3m

1

4m

1

=2.4m/s
