Which statement best describes why the bridge buckles when there isn't a joint ?
a. Temperature causes expansion and contraction of the roadway, which is limited without a joint
b. The metal in the joint is not affected by temperature, so without it bridges buckle
c. The material of the roadway doesn't expand under temperature
d. Joints increase the strength of the roadway to prevent the weight of cars and trucks from causing the bridge to buckle

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
