Question

A car moves in a straight line from rest at t=0. It accelerates with 2m/s2
Solve the following table Time ? Displacement- 25 m Velocity ?

Answer 1

Answer:

Final Velocity is 7.07 m/s;

Time taken is 3.53 seconds.

Explanation:

Given,

Initial Velocity (u) = 0 m/s

Acceleration (a) = 2 m/s²

Displacement (S) = 25 m            ..... Assuming Distance = Displacement

= v² = u²+2aS                             .... 'v' is the Final Velocity here.

= v² = 0²+2*25

= v² = 50

= v = √50 m/s

= v = 7.07 m/s

Time (t) = v = u+at

= 7.07 = 0+2t

= 7.07 = 2t

= t = 3.53 s

Hope this helps.
