Arectangular garden has a perimeter of 172 feet. the length of the garden is 24 feet more than the width. what are the dimensions of the garden? (recall the formula p = 2l + 2w.) a.62 ft by 86 ft c.55 ft by 79 ft b.31 ft by 55 ft d.74 ft by 98 ft

Amass weighing 16 pounds stretches a spring 8/3 feet. the mass is initially released from rest from a point 2 feet below the equilibrium position, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 1/2 the instantaneous velocity. find the equation of motion if the mass is driven by an external force equal to f(t)=cos(2t).
