Two cars, A and B, start at the same point. A travels north at 10 mph and B at 8 mph due

southwest. Find in what direction and rate by which car B is moving, with regards to car A. 

A fluid temperature rise of 18°C in the fluid cooled condenser is equivalent in °F to:

How many seconds would it take for a 4.50kw motor to raise a 175.kg boiler to a height of 15.0m?

(a) the displacement x, in m, from the equilibrium position of a particle moving with simple harmonic motion, is given by, x= 0.05 sin 6t, where t is the time, in s, measured from an instant when x= 0. (1) state the amplitude of the oscillations. (2) calculate the time period of the oscillations and the maximum acceleration of the particle.

(b) A mass hanging from a spring-suspended vertically is displaced a small amount and released. By considering the force on the mass at the instant when the mass is released, show that the motion is simple harmonic and derive an expression for the time period. Assume that the spring obeys Hooke's law.

A wire with a mass of 64 g and 1 m long floats horizontally in magnetic field. If

B = 1.6x10^-2 T is at the direction perpendicular to the wire, calculate the value of current in the wire with the aid of a diagram.

a particle moving with SHM has a speed of 8.0ms^-1 and an acceleration of 12ms^-2 when its is 3.0m from its equilibrium position. Find : (a) the amplitude of the motion, (b) the maximum velocity, (c) the maximum acceleration.

a particle moves with shm of period 4.0s and amplitude 4.0m. its displacement from the equilibrium position is x. find the time taken for it to travel: (a) from x=4.0m to x= 3.0m, (b) from x=-4.0m to x=3.0m, (c) from x=0 to x=3.0m, (d) from x=1.0 to x= 3.0m.
