A scooter acquires a velocity of 36 km h to the power of minus 1 end exponent in 10 seconds just after the start. calculate the accelaration of the scooter.

From the equation of motion, we get,

v = u + a t

Initial velocity, u=0                  [ Since, body starts from rest ]

Final velocity, v=36 km/h = 36 x Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.                  [1 km/h=Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.]

Therefore, v = 10 m/s

t = 10 sec

v = u + a t

v - u = a t

Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.

Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.=a

Therefore, a = 1 m/s2

Hence, the acceleration of the scooter is 1 m/s2.

why is it necessary for acceleration to be based on velocity but not on speed? why we dont consider the increasing speed of rectilinear motion as acceleration? why is it so in the first place?
