Question

A bike start with speed of 20km/h and it's acceleration is 10km/h for 30 minute find final velocity of bike​

Answer 1

Speed or initial velocity (u) 20kmph

20x 5/18 =50/9 m/s =5.55 m/s

Acceleration(a)= 10km/hr^2 (10 x 1000)/

3600 x 3600= 1/1296 m/s^2

Time (t) 30 minutes =1800 seconds

Final velocity(V) = u at

v =50/9 + 1800/1296

=> v=6.94 m/s

Answer 2

Speed or initial velocity (u)= 20kmph = 20× 5/18 = 50/9 m/s = 5.55 m/s

Acceleration(a)= 10km/hr^2 = (10 × 1000)/3600 × 3600 = 1/1296 m/s^2

Time(t) = 30 minutes = 1800 seconds


Final velocity(v) = u + at
=> v = 50/9 + 1800/1296
=> v = 6.94 m/s
