A cheetah accelerates from 38 m/s to 41 m/s. in 2 second A skunk accelerate from rest to 3 m/s also in 2 second. (a) Find the acceleration (magnitude only) of the skunk. (b) Determine the acceleration (magnitude only) of the cheetah. (c) During this 2 second, does the cheetah travel farther than the skunk

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.

What are the dimensions of the cross section that passes through the points a, f, g, and d?

Atoaster oven has a resistive heating element. the average rate at which it dissipates energy as thermal energy is 1.00 \(\rm kw\). in the united states, emf amplitude in household circuits is \(\mathcal e_{\max}\) = 170 \({\rm \; v}\) and the \(\rm ac\) oscillation rate is 60 \(\rm hz\). part a what is the root-mean-square current through the heating element?
