The function x = (3.0 m) cos[(3πrad/s)t + π/4 rad] gives the simple harmonic motion of a body. at t = 6.1 s, what are the (a) displacement, (b) velocity, (c) acceleration, and (d) phase of the motion? also, what are the (e) frequency and (f) period of the motion?

Ineed with these 2 questions. you.

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude
