Question

the distance travelled by a particle in time t is given by s is equal to 2.5 metre per second t2 find the instantaneous speed at t= 5sec with full explanation ​

Answer 1

25 m/s

Step-by-step explanation:

s = (2.5 m/s²) t²

Velocity is the first derivative of position with respect to time.

v = ds/dt

v = (5 m/s²) t

At t = 5 s:

v = (5 m/s²) (5 s)

v = 25 m/s
