A lab technician uses a cylindrical projectile launcher to throw rubber spheres horizontally at a nearby vertical target. Using a radar gun, she establishes that a sphere with a mass of 0.150 kg and diameter of 6.00 cm has its speed reduced by 10% due to air resistance when the initial speed is of 46.0 m/s as it travels from the launch site to the target a distance of 18.0 m away. Due to the air resistance, a change in temperature occurs initially only for the air in a cylinder equal to the volume of air swept out by the sphere. Determine the maximum possible temperature change (in °C) for this air when the temperature of the air is 20.0°C. To find the greatest possible temperature change, you may make the following assumptions: air has a molar specific heat of C₁ = (-)R, an equivalent molar mass of 28.9 g/mol, and a density of 1.20 kg/m³. °C

An astronaut lands on a newly-discovered planet (without an atmosphere). As an experiment, she throws vertically upwards a pure vanadium sphere of radius 2.0 cm and density 5.5 × 103 kg m-3 with an initial speed of 3.0 m s-¹. The point of release is 1.2 m above the ground. She observes the sphere to travel 4.8 m before it starts falling to the ground. Calculate the kinetic energy of the projectile just as it hits the ground. Kinetic energy = J.

You are designing a single-stage rocket to launch a 300-kg satellite. Assume the rocket engine's I, as 460 sec. Use g=9.8 m/sec² for the gravity acceleration constant. sp (a) Assume that you are launching the satellite in free space with no gravity and no aerodynamic drag, and your rocket has zero mass except the pronellants and the satellite. Calculate the mass of the propellants to give AV = 7.784 km/sec. (b) Assume the same in (a) except that the rocket's mass is proportional to the propellants: 15% of the propellants. Calculate the mass of the propellants for AV=7.784 km/sec. (Of course, the rocket's mass remains the same after the burn)
A particle P of mass m = 0.56 kg is released from rest at a point h = 7 m above the surface of a liquid in a container. P falls through the air into the liquid. Assume there is no air resistance and there is no instantaneous change in speed of P as it enters the liquid. When P is at a distance of d = 0.71 m below the surface of the liquid, P's speed is v = 4.9 m/s. The only force acting on P due to the liquid is a constant resistance to motion of magnitude R N. Find the following: v1: The speed (in m/s) of P the moment just before it strikes the surface of the fluid.a1: The magnitude of the deceleration (in m/s2) of P while it is falling through the liquid.R: The magnitude of the resistance force (in N). The depth of the liquid in the container is dp = 3.9 m. P is taken from the container and attached to one end of a light inextensible string. P is placed at the bottom of the container and then pulled vertical upwards with a constant acceleration, a2. The resistance force to motion R N…
A team of astronauts is on a mission to land on and explore a large asteroid. In addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. With what minimum initial speed ?esc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? Assume that the asteroid is approximately spherical, with an average density ?=2.93×106 g/m3 and volume ?=1.94×1012 m3 . Recall that the universal gravitational constant is ?=6.67×10-11 N·m2/kg2 .vesc = ? m/s

To test the speed of a bullet, you create a pendulum by attaching a 5.00 kg wooden block to the bottom of a 2.40 m long, 1.40 kg rod. The top of the rod is attached to a frictionless axle and is free to rotate about that point. You fire a 10 g bullet into the block, where it sticks, and the pendulum swings out to an angle of 34.0°. What was the speed of the bullet?
