Answer:
if you need to get the work=force×displacement or if you need the velocity=displacement÷time taken
Answer:
Final velocity at the top of the ramp is 6.58m/s
Explanation
Check the attachment
A bell or a siren or a ring in somewhere
Answer:2800000j
Explanation:
For us to know the kinetic energy of the vehicle,
Where m is the mass
And v is the velocity
Then, K.E=1/2mv^2
While, K.E=1/2×3500×40^2
Therefore, our answer will now be
K.E=2800000j
