A dragster's top acceleration is 60m/s2. If it accelerates for 3 seconds from the starting line, how fast will it be going

180 m/s

Explanation:

acceleration = 60 m/s2

time = 3 secs

u(initial velocity) = 0 m/s

v(final velocity) = ?

equation used is = v = u + at

0 + 60*3

v = 180 m/s

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
