Question

· A car starting from rest acqures a velocity of 50m/s in 10 s.
a.what is the acceleration of the car
b.what is the displacement travelled by the car​

Answer 1

Explanation:

u = 0

v = 50 m/s

t = 10s

acceleration = v-u / t

= 50 / 10

= 5m/s^2

displacement = ut + 1/2 at^2

= 0 + 1/2 × 5 × 10^2

= 1/2 × 5 × 100

= 250 m

hope it helps :)

Answer 2

Answer:

5 m/s^2

Explanation:

A bus acquires a velocity of 50m/s in 10 seconds. What is its acceleration?

You can use SUVAT equations to solve this assuming a few things…

The bus started stationary

The acceleration is constant (Given you want a single answer this is probably true)

The equation we want is:

v=u+at

v is the final velocity and u is the initial velocity

a is acceleration and t is time elapsed

Rearranging gives:

a=(v−u)/t

or

v/t

You answer is 5 m/s^2
