A block of mass 2 kg placed on a long frictionless horizontal table is pulled horizontally by a constant foerce F. It is found to move 10 m in the first two seconds. Find the magnitude of F.

Explanation

Given, m-2kg S= 10 m
Let accelertation =a
and initial velocity u=0
We know, `S= ut+ 1/2 at^2`
`rarr 10= 1/2 alpha(2^2)`
` 10=2a`
`- a=5m/s^2`
`:. Force, F=ma = 2xx5 = 10 N`.
