∫vdv from 8.33E-4 to v = ∫ads from 0 to 300
v^2=vnot^2+2a(snot-s)=(8.33E-4)^2+2(.4)(300)
v=15.49m/s
This is what I did but the answer is wrong and not sure what I did wrong.
Please help,
A motorcycle patrolman starts from rest at A 5 seconds after a car, speeding at the constant rate of 124 km/h, passes point A. If the patrolman accelerates at the rate of 6.4 m/s2 until he reaches his maximum permissible speed of 147 km/h, which he maintains, calculate the...
Please help,
A vehicle enters a test section of straight road at s = 0 with a speed of 50 km/h. It then undergoes an acceleration which varies with displacement as shown. Determine the velocity v of the vehicle as it passes the position s = 0.30 km.
Thanks!
