Answer:
300m
Step-by-step explanation:
step one
given data
initial speed u= 15m/s
final speed v= 45m/s
time taken to attain final speed= 10seconds
Step two:
Let us first solve for the acceleration
a= Δv/t
a= 45-15/10
a=30/10
a= 3m/s
applying the equation of motion

substituting our given data

collect like terms
2025-225=6s
1800=6s
divide both sides by 6
s=1800/6
s=300m
