Question

the x and y coordinates of a particle at any time t are x=5t-3t2 and y=5t rept where x and y are in meter and t in second the speed of the particle at t=1 second is

Answer 1

Answer:

X=-1

Explanation:

X=5t-3t2

X=5(1)-3(1)2

X=5-6

X=-1

Answer 2

Answer:

this question is completely a numerical but it is not if u think u very tough

so this question answer is =√26 m/s
