Question

find acceleration and velocity at 2 sec of the motion of an object having displacement function x(t) = (5t^2+3t-2) m​

Answer 1

given : t = 2 sec

so ,

finding Displacement :-

put t = sec in given Equation

x(t) = (5t² + 3t - 2)m

so ,

x(2) = 5(2)² + 3(2) - 2 = 5(4) + 6 - 2 = 20 + 4 = 24 m

Answer 2

hope this will help you buddy
