Question

a body of mass 1kg is kept at rest at a constant force of 6.0 Newton start acting on it find the time taken by the body to move through a distance of 12 m

Answer 1

F=ma

6N=1Kg a

a= 6 N/Kg

=>a=6m/s2

time=distance/speed


time=12/6
time=2sec

please mark as brainliest

Answer 2

Given :-

Mass → 1 kg

Force → 6 N

So, Acceleration → ?

_____

Initial Velocity → 0 m/s

Distance Travelled → 12 m

Time Taken → ?

To Find :-

The acceleration produced

The time taken

Solution :-

As we know ,

F = ma

→ 6 N = 1 kg × acceleration

→ So, Acceleration = 6.0 m/s²

[ Formula Used :- ]

s = ut + ½ at² ★

Here,

s = 12 m

u = 0 m/s

t = ?

a = 6 m/s²

→ 12 m = 0 × t + ½ × 6 m/s² × t²

→ 12 m = 0 + 3 m/s² × t²

→ 12 m = 3 m/s² × t²

→ 4s² = t²

→ t = √4s²

→ t = 2s

So, The time taken was 2 s
