A body starts slipping down an incline and move, half meter in half second. How long will it take to move the next half meter?

Question

Philoid · Accepted Answer

let the mass of the body= m

Angle of inclination = θ

Acceleration of the body= a

According to the free body diagram,

Substituting the value of R in the above equation,

In first half meter, the distance covered s= 0.5 m

Time taken t= 0.5sec

Initial velocity u= 0

Using equation of motion,

s=ut + at²

m/s²

For next half meter,

Velocity u=2 m/s

Acceleration a= 4 m/s²

Distance s= 0.5m

Using s=ut + at²
