- A car's bumper is designed to withstand a 5.76 km/h (1.6 m/s) collision with an immovable object without damage to the body of the car. The bumper cushions the shock by absorbing the force over a distance. Calculate the magnitude of the average force (in N) on a bumper that collapses 0.255 m while bringing a 880 kg car to rest from an initial speed of 1.6 m/s. (Enter a number.) NCan you help me with this problem?A block with a mass m is initially compressing a spring by x1 on a horizontal floor with friction. The spring has a spring constant k. The block is realeased from rest and travels a total distance of D including x1 and has a speed of v. what is the coefficent of kinetic friction between the floor and block?A 250 gram block is dropped from rest at a height of 1.2m onto a relaxed vertical spring that has a spring constant of k =2.5 N/cm. The block continues downward, compressing the spring until it reaches its lowest point. At the lowest point, how much has the spring been compressed? Please answer in units of meters.

What will be the maximum compression in the spring?A toy car of mass m is pushed against a spring, compressing it a distance d from its natural rest length. The spring exerts a force F(x) = −(kx + ßx5)ix, where x is the displacement from its equilibrium position at the origin. The car is then released from rest and slides on a table with coefficient of friction µ. (i) What is the car's speed when it reaches the origin? (ii) If the car detaches from the spring when it reaches the origin, derive an equation that could be solved to find the location of the car when it comes to rest (do not solve).

She plans to use a uniform elastic cord, tied to a harness around her body, to stop her fall at a point 11.0 m above the water. Model her body as a particle and the cord as having negligible mass and obeying Hooke's law. In a preliminary test she finds that when hanging at rest from a 5.00 m length of the cord, her body weight stretches it by 1.25 m. She will drop from rest at the point where the top end of a longer section of the cord is attached to the tower. (a) What length of cord should she use? m (b) What maximum acceleration will she experience? m/s²
