An object of mass 0.1 kg moves at a speed of 1.2 m / s towards a larger object of mass 1 kg that is at rest. After the collision, the smaller object bounces and moves at a speed of 0.85 m / s. Determine the velocity of a larger object after a collision.
A ball of mass 22 g moves to the left at a speed of 35 m / s. How much work needs to be done on the ball to start moving to the right at a speed of 35 m / s. When considering ignore any energy losses.

The largest mall in Africa by volume is Mall of Africa, South Africa.It measures approximately 631 m long, 707 yards wide,and 110 ft high. Calculate it's volume in cubic meter.
How many significant figures does the number 3.001×10^5 have?
Two planes are 2500km from an airport it takes one plane flying 50km/h faster 1 hour and 40 minutes Less than the other plane to reach airport find the speed of the two plane
4. Buoyancy. A slab of ice floats on a freshwater lake. What minimum volume (in m3) must the slab have for a 45.0 kg woman to be able to stand on it without getting her feet wet? (Density of ice = 917 kg/m3, Density of water= 1000 kg/m3)
5. Continuity Equation. A 14.0-cm inner diameter water main
furnishes water (through intermediate pipes) to a 1.00 cm inner diameter faucet
pipe. If the average velocity in the faucet is 3.00 cm/s, what will be the
average velocity (in cm/s) it causes in the water main?
6. Bernoulli’s Principle. Water inside an enclosed tank is
subjected to a pressure of two atmospheres at the top of the tank. How fast (in
m/s) will water move out of a small hole 3.00 m below the top surface of the
water? The density of water is 1000 kg/m3.
1. Density. A piece of copper whose density is 8.93 g/cm3 has a mass of 180 g in air and 162 g when submerged in a certain liquid. What is the mass density (in g/cm3) of the liquid?
2. Gauge Pressure. At what depth (in meters) in seawater is the gauge pressure 1.00 x 105 Pa? (density of seawater= 1025/kg/m3)
3. Pascal’s Principle. In a hydraulic press the small cylinder has a diameter of 8.00 cm, while the large piston has a diameter of 20.0 cm. If a force of 500 N is applied to the small piston, what is the force on the large piston, neglecting friction?
