3. What is the final speed of a bicyclist initially moving at 10m/sec who accelerates at a rate of 1.5 m/secfor 3.0
sec?​


Sagot :

Calculating Final Speed.

Given

  • Initial Speed (u) = 10 m/s
  • Acceleration (a) = 1.5 m/s²
  • Time (t) = 3.0 s
  • Final Speed (s) = ?

s = u + at

s = (10 m/s) + (1.5 m/s²)(3.0 s)

s = (10 m/s) + (4.5 m/s)

s = 14.5 m/s
