Given :
- an object travels 20m in 2 sec and then another 16 m in 2 sec
To Find :
- what is the average speed of the object
Solution :
Total distance travelled
==> 20 + 16
==> 36
total time taken
==> 2 + 2
==> 4
Average speed = Total distance travelled/total time taken
==> 36/4
==> 9 m/sec
Extra information :
- Speed = d/t
- F = m. a
- a (bar) = v - v_0/t = Δv/Δt
- w = F x d
- P = W/Δt
- V = 1R
- PE = mgh
- p = mv
