Question

A cyclist travels at a constant velocity of 4.5 m/s westward then speeds up with a steady acceleration to 2.3 m/s^2 calculate the cyclist speed after accelerating for 5.0 s

Answer 1

Final velocity after 5 sec is 16 m/s

Given that;

Initial velocity = 4.5 m/s

Constant acceleration = 2.3 m/s²

Time taken = 5 second

Find:

Final velocity

Computation:

Using first equation of motion;

v = u + at

v = 4.5 + (2.3)(5)

v = 4.5 + 11.5

v = 16 m/s

Final velocity = 16 m/s
