A.| A family of four with a total mass of 350 kg steps into a 1350 kg car, and the springs compress 3.65 cm. Question: How far will the car lower if an additional passenger gets in bringing the mass to 425 kg instead of 350 kg?

The figure shows a 100kg block being released from rest from a height of 1m. It then takes 0.90s to reach the floor. What is the mass of the other block (m)? The pulley has no appreciable mass or friction. Please answer in kg

9. A 1200 kg car drives at an initial velocity vo = 45 m/s along a highway. At t = 0, the driver releases the gas, and the car slows to a stop due to a drag force given by Fdrag = -b v, where b = 15 kg/s³. Derive a function for the car's velocity as a function of time and solve it for the car's velocity at 10, 20, and 30 s.

If you drop a sheet of paper and a book side by side, the book falls faster than the paper. Why?

Astronaut Pam Melroy, history's third woman space shuttle pilot, flew the space shuttle Discovery to the INternational Space Station to complete construction in October of 2000. To unlock from the space station Pilot Melroy released hooks holding the two spacecraft together and the 68,000 kg shuttle pushed away from the space station with the aid of four large springs. If the 73,000 kg space station moved back at a speed of .6 m/s, how fast did the shuttle move?

A 325-g model boat facing east floats on a pond. The wind in its sail provides a force of 1.45 N that points 25 north of cast. The force on its keel is 0.613 N pointing south. The drag force of the water on the boat is 0.750 N toward the west. If the boat starts from rest and heads east, what is its final speed by after it travels for a distance of 4.15 m? Uy = -14.4 m/s
