A particle is moving in two dimensions such that in Cartesian coordinates,
x = A(2at - sin(at))
y = A(1 - cos(at))
Where A and a are constants.
a) Discover the times at which the magnitude of the acceleration is maximum.
b) Discover the tangential component of acceleration (acceleration in the direction of motion) as a function of time.
c) Discover the normal component of acceleration (acceleration perpendicular to the direction of motion) as a function of time.
A total charge of 14 mC passes through a cross-sectional area of a nichrome wire in 1.4 s. I need to know how many electrons pass through the cross-sectional area in 23.0 s

Two parallel wires are 5 m long. They are seperated by a perpendicular distance of 1 cm and carry currents of 20 A, Find the interaction force between the wires
A low-power laser used in a physics lab might have a power of 0.40 mW and a beam diameter of 2.6 mm. Calculate the average light intensity of the laser beam
q1. an observer moving toward earth with a speed of 0.97 notices that it takes 5min for a person to fill her car with
A block is hung by a string from the inside roof of a van. When the van goes straight ahead at a speed of 29m/s, the block hangs vertically down. But when the van maintainsthis same speed around an unbanked curve (radius = 165 m), the block swings..
You're a production engineer in a cookie factory, where mounds of dough drop vertically onto a conveyer belt at the rate of one 14 mound every 2 seconds. What average force must the mechanism exert on the belt
After impact, the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.650, illustrate what was the speed of the bullet immediately before impact?
An ambulance traveling at 47 m/s approaches a car heading in the same direction at a speed of 37 m/s. At what frequency does the driver of the car hear the siren
suppose you made a 5.40 kiloOhm resistor from a carbonresistor and a Nichrome wire-wound resistor connected together so the total resistance is the sum of their separate resistances. Whatvalue should the carbon resistor have (at 0 degrees Celsius)..
Imagine Bob lives on the earth at rest. Sara is traveling past the earth with a velocity of 9600 m/s, Suppose that a photon of light is passing Sara instead of a meteor. Bob measures the photon speed to be c, the speed of light. What speed does Sar..
