Determine force constant of the spring
An elevator car of mass 835 kg falls from rest 3.30 m, hits a buffer spring, and then travels an additional 0.430 m, as it compresses the spring by a maximum of 0.430 m. What is the force constant of the spring?

A horse canters away from its trainer in a straight line, moving 119 m away in 13 s. It then turns abruptly and gallops halfway back in 4.0 s. Calculate its average speed in m/s.
A uniform soda can of mass 0.136 kg is 12.2 cm tall and filled with 1.26 kg of soda. Then small holes are drilled in the top and bottom (with negligible loss of metal) to drain the soda. What is the height h of the CM of the can and contents (d) I
You drive on Interstate 10 from San Antonio to Houston, half the time at 56 km/h and the other half at 94 km/h. On the way back you travel half the distance at 56 km/h and the other half at 94 km/h.
A car initially traveling at 25.9 m/s undergoes a constant negative acceleration of magnitude 1.60 m/s2 after it brakes are applied. How many revolutions does each tire make before the car comes to a stop, assuming the car does not skid and the ti
Now suppose the friction is sufficient to keep the car from skidding. Calculate the magnitude of the normal force exerted on the car by the road's surface.
