Object A has a position as a function of time given by A(t) = (3.00 m/s)t + (1.00 m/s2)t2. Object B has a position as a function of time given by B(t) = (4.00 m/s)t + (-1.00 m/s2)t2. All quantities are SI units. What is the distance between object A and object B at time t = 4s?
Illustrate what is the magnitude of the net torque on the wheel due to these three forces for an axis perpendicular to the wheel and passing through its center?
What is its initial velocity as it leaves the ground. Two particles are fixed on an x axis.
Far in space, where gravity is negligible, a 485kg rocket traveling at 95.0m/s fires its engines. It shows the thrust force as a function of time. The mass lost by the rocket during these 30 s is negligible.
Find out the minimum acceleration of the antelope.
The density of water is 1000kg/m^3 or 8.33lbm/gallon, the mass flow rate is 494838.83 kg/s and goes through a turbine generator that has 0.80 efficiency
A 99 kg man lying on a surface of negligible friction shoves a 71 g stone away from himself, giving it a speed of 4.0 m/s. What speed does the man need as a result.
When the space shuttle (mass of the shuttle=2*10^6kg) was at the outer limit of Earth's atmosphere (distance= 350km above Earth's surface), astronauts measured the gravitational force from Earth to be equal to 1.7*10^7 newtons. Find the gravitatio..
An east-west electric power line carries a 500-A{\rm A} current toward the east. Determine the direction of this magnetic field at Earth's surface directly under the wire
A 25- sample of an ideal gas with is at 250 and 50. The gas is compressed isothermally to one-third of its original volume, then heated at constant volume until its state lies on the adiabatic curve that passes through its original state, and then al..
Calculate the time the microgel would require to recover to 99% of its initial height after the stress is removed. Determine the potential barrier for the molecule aggregation?
A dockworker applies a constant horizontal force of 82.0N to a block of ice on a smooth horizontal floor, What is the mass of the block of ice
A flat sheet of crystalline quartz has a thickness of 3.7cm. It is on top of a flat sheet of diamond that has a thickness of 2.6cm. Light strikes the crystalline quartz vertically and travels through it and then through the diamond.
