SUMMARY

The discussion focuses on calculating the average acceleration of a dragster with a total mass of 905.5 kg, which accelerates from rest to a speed of 25 m/s in 0.61 seconds. The correct kinematic equation to use is v = v₀ + at, where v₀ is the initial velocity (0 m/s), v is the final velocity (25 m/s), and t is the time (0.61 s). By rearranging the equation to solve for acceleration (a), the average acceleration is determined to be approximately 40.98 m/s².

A dragser and a driver together have a mass 905.5 the dragster, starting at rest, attains a speed of 25 m/s in .61s. find the average acceleration of the dragster during the time interval. answer in units of m/s.

ok I am assuming we have 3 variable for a kinematic equation t=.61s, v.=0, and v=25m/s so i would solve for acceleration using v=v.+at ... right? If not I need some help please.

v=v.+at is correct, as is t=.61s, v.=0, and v=25m/s, which gives . . .
