The weight of passengers on a roller coaster increases by 51 % as the car goes through a dip with a 39 radius of curvature. What is the car's speed at the bottom of the dip?
A vertical scale on a spring balance reads from 0 to 205 N. The scale has a length of 10.0 cm from the 0 to 205 N reading. A fish hanging from the bottom of the spring oscillates vertically at a fr
An airplane is heading due south at a speed of 485 km/h. A wind begins blowing from the southwest at a speed of 100 km/h (average). What is the velocity (magnitude and direction) of the plane relativ
Imagine that a mad scientist invents a death-ray that destroys a person's ciliary, sphenopalatine, and submandibular ganglia (and nothing else). Discuss all the symptoms the victim would show. Would t
A 75-kg lumberjack stands at one end of a 383-kg floating log, as shown in the figure. Both the log and the lumberjack are at rest initially. If the lumberjack now trots toward the other end of the
A motorist traveling at 17 m/s encounters a deer in the road 48 m ahead. If the maximum acceleration the vehicle's brakes are capable of is -5 m/s2, what is the maximum reaction time of the motoris
the Hall voltage is 0.337 µV. What is the unknown magnitude of the field? B.If the thickness of the probe in the direction of B is 1.88 mm, calculate the charge-carrier density (each of charge
Animals obtain energy through a series of chemicals reactions in which sugar (C6 H12 O6 ) and oxygen gas (O2 ) are reactant. This produces water (H2O) and carbon dioxide (CO2) as waste products. How m
A 5kg ball, moving to the right at a velocity of 2m/s on a frictionless table, collides head on with a 7.5kg ball. Find the final velocities of the balls if the collision is completely inelastic.
A cat runs along a straight line (the x-axis) from point A to point B to point C, as shown in Fig. 2.1. The distance between points A and C is 5.00 m, the distance between points B and C is 10.0 m,
A conducting rod of length moves on two horizontal, frictionless rails, as in the figure. A constant force of 1.00 N moves the bar at 2.00 m/s through a magnetic field B that is directed into the mo
