What acceleration would the occupants feel on a flat road? I agree it is not completely clear, but I would guess you are to interpret the felt acceleration in terms of the forces felt.KLI897 said:Homework Statement
A car travels over a hump in the road of radius 20 meters. How fast is the car traveling if the occupants feel a net acceleration of 3.8 m/s2
Homework Equations
a = v2/r
v = √ar
The Attempt at a Solution
I did this but according to my teacher this isn't correct.
v = √(3.8 m/s2)(20 m)
v = 8.718 m/s
Velocity can be calculated by multiplying the radius by the acceleration and taking the square root of the product. The formula is V = √(r x a).
The unit of measurement for velocity is meters per second (m/s).
Yes, velocity can be negative. Negative velocity indicates that the object is moving in the opposite direction of the positive direction that was chosen as the reference point.
The greater the acceleration, the faster the velocity will change. This means that the object will speed up or slow down at a faster rate.
Other variables that can affect an object's velocity include air resistance, friction, and external forces such as gravity or a push/pull force.
