Q1. A Toyota Prius driving north at 59.0 and the VW Passat driving south at 37.0 are on the same road heading toward each other (but in different lanes). (We take the positive direction to be north.)
Q2. A child in danger of drowning in a river is being carried downstream by a current that has a speed of 2.75 km/hr. The child is 0.560 km from shore and 0.750 km upstream of a boat landing when a rescue boat sets out. If the boat proceeds at its maximum speed of 20.1 km/hr relative to the water, what heading relative to the shore must the pilot take?
Two non conservative forces are present: friction does -2.00 104 J of work on the car, and a chain mechanism does +3.00 104 J of work to help the car up a long climb. What is the transform in the car's kinetic energy, ΔKE = KEf - KE0, from A to B.
What is the least speed the block must have at the top of the loop to make it around the loop-the-loop without leaving the track
What is vertical component of the acceleration
A block of mass 2.7 kg being released from rest on a 1m frictionless plane, inclined at an angle of 40 degree. The block sided down the inclined and struck second block mass of 3.7 kg. If the two blocks stick together, with what speed would they move..
A 60kg bicyclist rides his 7.8kg bicycle with a speed of 16m/s. How much work must be done by the brakes to bring the bike and rider to a stop.
Evaluate maximum altitude?
What is final speed of the block
The parallel metal plate of a capacitor is separated by a distance of 0.5cm and is connected to a 90v battery. Discover an electric field between them and the surface charge density .
Displacement d2 is in the xz plane 30° from the positive direction of the x axis, has a positive z component, and has magnitude 1.10 m.
Hair dryer draws a current of 9.2a. How long does it take 1.9*10^3 C of charge pass through? How many electrons does this represent.
A man pushes a lawnmower for 13.1 m along a handle that makes a 28.2° angle with the ground. He pushes with a force of 42.8 N even as the force of friction between the lawnmower and the ground is 13.7 N.
Determine the resolution limit set by diffraction . what average force do you need to apply to stop the sled? Utilize the concepts of impulse and momentum.
