Take the direction west to be positive, and east to be negative. What is the average acceleration of a jet ski that goes from rest to 10 m/s west in 4 s? Question 4 options: 2. 5 m/s2 -2. 5 m/s2 0. 4 m/s2 -0. 4 m/s2.

Sagot :

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]

What is average acceleration?

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.
