A BLOCK OF MASS 500G IS PULLED FROM REST ON HORIZONTAL FRICTIONLESS BENCH BY STEADY FORCE F AND TRAVELS 8M IN 2S .FIND THE ACCELERATION. PLEASE ALSO GIVE ME EXPLAINATION. IT IS OF PHYSICS

GIVEN

Mass of block = 500 g

Initially at rest

Distance travelled = 8 m

Time = 2 seconds.

TO FIND

a) Acceleration of block

b) Value of force

SOLUTION

We have,

• Distance travelled (s) = 8 m

• Initial speed (u) = 0

• Time (t) = 2 s

• Mass (M) = 500 g

We will use 2nd equation of motion :

b) We now have,

• Mass of block (M) = 500 g = 0.5 kg

• Acceleration of block (a) = 4 m/s²

Now we will use 2nd law :
