Average acceleration is defined by the change in the velocity with respect to time.
The average acceleration of a jet ski that goes from rest to 10 m/s west in 4 s will be [tex]\rm{2.5 m/s^{2}[/tex]
Average acceleration is defined by the change in the velocity with respect to time. It is given by,
[tex]\rm{a = \frac{v-u}{t} }\\[/tex]
Where,
a is the average acceleration
u is the initial velocity
v is the final velocity
t is the time taken
Assumptions
Take the direction west to be positive, and east to be negative.
given,
a =?
u =0 m/sec
v =10 m/sec
t = 4 sec
[tex]\rm{a = \frac{v-u}{t} }\\[/tex]
[tex]\rm{a = \frac{v-u}{t} }\\\\\rm{a = \frac{10-0}{4} }\\\\\rm{a = 2.5 m/s^{2}[/tex]
Hence the average acceleration of a jet ski that goes from rest to 10 m/s west in 4 s will be 2.5 m/s.
