Question

If a drag racing motorcyclist has an initial speed of 10 m/s, and then he/she

accelerates for 15 seconds at 15 m/s2, what is the velocity after 15 seconds?
O 30 m/s
O235 m/s
O225 m/s

Answer 1

235 m/s

Step-by-step explanation:

v = u + at

where v = final speed,

u = initial speed (10 m/s),

a = acceleration (15 m/s²),

t = time taken (15 s).

Substituting into the formula:

v = 10 + (15 x 15)

v = 10 + 225

v = 235 m/s
