mass = 1.8kg
given equation in problem x(t) = (7.40cm)cos[(4.16s^-1)t - 2.42]
*when i tried solving i converted 7.40cm to 0.074m
find the position of the mass at t = 1.00s
x(t) = (7.40cm)cos[(4.16s^-1)t - 2.42]
The Attempt at a Solution
i've been working on this problem for a while, i haven't been able to get the correct answer, even when i made sure to check units and make necessary unit conversions. i made sure my units were in radians (within the cosine) but it keeps yielding the wrong answer, i was able to find velocity and acceleration from the given equation, just not position.
i thought this problem would be just plug and chug, when i stuck t=1.00s it still hasn't given me the correct answer, i got -0.01 and 0.074, both were incorrect
