Question

The final velocity of a truck that is initially traveling at 10 m/s and travels 500m over

the course of 13 seconds

Answer 1

this is an amazing question

Answer 2

123.75 m/s

Step-by-step explanation:

Given:

• Initial velocity (u) = 10 m/s
• Distance travelled(S) = 500 m
• Time(t) = 13 s

To Find:

• Final velocity,ie, v.

Formula used:

• S = ut + at^2/2

where,

S is distance travelled

u is initial velocity

v is final velocity

t is time taken

• v = u + at

where,

v is final velocity and rest meaning is written above.

Let the acceleration of truck be a

Using the above formula, we get

500 = 10*13 + a(13)^2/2

370 = 169a/4

a = 8.75 m/s^2

So, Putting value of a in v = u + at, we get

v = 10 + 8.75*13

v = 123.75 m/s

So, the final velocity will be 123.75 m/s.
