The CM of an empty 1200-kg car is 2.50 m behind the front of the car. A.)How far from the front of the car will the CM be when two people sit in the front seat 2.90 m from the front of the car, and three people sit in the back seat 4.00 m from the front? Assume that each person has a mass of 70.0 kg. Express your answer to three significant figures and include the appropriate units.

Use the following information to estimate the mass of a surfboard. Maximum displacement of the boy is 0.9 m Maximum displacement of the surfboard is 1.3 m Assume the boy and surfboard system are isolated. The mass of the boy is 33.3 kg. The formula for the center of mass is… m1x1+m2x2/m1+m2

Example B: Three people stand around not doing their physics homework as shown below. Find the distance of the center of mass of the 3 person system from leftmost person. M₁= 70 kg 4 m M₂=60 kg 6 m M₂= 82 kg

In the figure below, the masses of each object are: m₁ 1.00 kg, m₂ = 4.00 kg, m² = 6.00 kg. The labeled distances are: d₁ = 25.0 cm, d₂ = 104 cm, d3 = 60.0 cm (where d is the x distance for the center of the block). The height of each block is h₁ = 19.0,h₂ = 28.0 cm, and the h3 = 12.0 cm. Assume the center of mass for each individual object is at the center of the object. Hint: Consider the final center of mass (x,y) relative to the axes shown in the figure. Note the positions of the boxes relative to the axes and to one another. Determine the positions, x and y, of the center of mass for the system below. Enter to 3 significant figures Center of mass (x, y): ( d1 m1 d3 d2 h1 ✔cm = m3 m2 h2 ✔ cm) 11h3 X
