Question

An Object moves through 10m in 2min and next 2000m at a speed of 1200 s. calculate its average speed.​

Answer 1

v = 16.52 m/s.

Step-by-step explanation:

Initially, an object moves through 10 m in 2 min.

Then, he moves 2000 m at a speed of 1200 m/s. Let t₂ is the time during for this duration.

`t=(d)/(s)\\\\t=(2000\ m)/(1200\ s)\\\\t=1.67\ s`

So, average speed,

`v=(d_1+d_2)/(t_1+t_2)\\\\v=(10+2000)/(120+1.67)\\\\v=16.52\ m/s`

So, its average speed is 16.52 m/s.
