Find the acceleration of the dragster
A VW Beetle goes from 0 to 64.8 mi/h with an acceleration of +2.34 m/s2.
(a) How much time does it take for the Beetle to reach this speed?
(b) A top-fuel dragster can go from 0 to 60.0 mi/h in 0.600 s. Find the acceleration of the dragster.

Calculate the formal charge on the indicated atom in each of the following molecules or ions. Some molecules may have more than one possible resonance structure, each resulting in a different possible formal charge on the indicated atom.
Each pump is rated at 515 m3/min when producing a pressure rise equal to a pressure head of 20 meters of water. Treating the pumps as adiabatic, calculate the minimum power required to drive each pump (in kW and hp).
A block of mass m = 3.0 kg is attached to a spring of constant k = 240 N/m. It can slide along a board tilted at an angle theta = 37° to the horizontal. Initially the block is released from rest when the spring is compressed by x 0 = 30 cm. (a
Calculate the final temperature and the specific work required (i.e., work per kg of flow). Compare this to an isentropic compression from the same inlet conditions to the same final pressure.
A top-fuel dragster can go from 0 to 60.0 mi/h in 0.600 s. Find the acceleration of the dragster.

A golfer imparts a speed of 30.0 m/s to a ball, and it travels the maximum possible distance before landing on the green. The tee and the green are at the same elevation. a) How much time does the ball spend in the air?
At that point the flow rate is 4 kg/s through a 4-cm-diameter pipe. Design criteria call for the average flow velocity to be less than 15 m/s. Will these conditions meet the design?
11.50 kg block of metal measuring 12.0 cm x 10.0 cm x 10.0 cm is suspended from a scale and immersed in water. The 12.0 cm dimension is vertical and top of the block is 5.75 cm below the surface of the water. what are the forces acting on the bott
