Question

4. Plot the distance time graph When a body starting form rest and acquire the velocity 20
m/s after 5 sec. Also find the distance cover by body
02​

Answer 1

Explanation:

Vo = 0 m/s

Vf = 20 m/s

t = 5 s

d = ?

d = (Vf²)/2a

a = (Vf -Vo)/t

a = ( 20 m/s - 0 m/s)/5s

a = 20 m/s / 5s

a = 4 m/s²

d = (20 m/s)²/ (2 × 4m/s²)

d = 400 m²/s² / 8 m/s²

d = 50 m ANSWER
