Best ResponseYou've already chosen the best response.0So 3+4(5)^2=97. The instantaneous velocity would be 97? @Hero

Best ResponseYou've already chosen the best response.1Actually, you should find v(t) first, then evaluate v(5).

Best ResponseYou've already chosen the best response.1You have to calculate s'(t) first. In other words, take the derivative of s(t) to get v(t).

Best ResponseYou've already chosen the best response.0The derivative of 3 + 4t^2 is 8t. so 8t=vt? Then what?

Best ResponseYou've already chosen the best response.0so 8*5=40. so the instantaneous velocity is 40?

Best ResponseYou've already chosen the best response.0But I have the correct number, 40, correct? @Hero
