Answer to Question #215383 in Mechanics | Relativity for Joe

Question

a JetSki initially travelling at 6.4m/s [W35N] soon accelerates at a rate of 2.2m/s^2 [S] for four seconds. Calculate the final velocity of the Chesky

Answer 1

V= u+at

V=final velocity

U=initial velocity

a=acceleration

t=time

V = 6.4m/s + 2.2m/s/s × 4s

V = 6.4m/s + 8.8m/s

= 15.2m/s

Final velocity = 15.2m/s.
