driving at 30 m/s susan enters a one-lane tunnel, and
155 m ahead of her, a van is going at 5 m/s
she deaccelerates at -2 m/s
1. will there be a collision?
2. if so determine how far into the tunnel it will be and at what time it occurs
3. if not determine the distance between susan and the van

please show all work and use one of the five kinematics acceleration equations..thanks!!!

Can we build a playground over an existing parking lot without tearing up the asphalt that is there? We will be using a dirt base with permalife pour and fill for impact absorption. Can anyone tell me if there is a need for the asphalt to be removed if it is covered in such a manner? This is a school build and will require inspection.

a speeding car is traveling at 92 km/h towards a police car at rest, facing the same direction as the speeding car. If cop car begins accelerating when speeding car is 250 m behind the cop car,then what must the cop car's acceleration be in order for the cop car to reach the speeding car's velocity at the moment the speeding car catches up? Assume that the speeding car doesn't slow down.

Please show all work necessary; Use one of the five kinematics equations...thanks!!!
