Submission 3 (0.75/1 points) Friday, June 21, 2024 09:25 PM Consider the 65.0 kg ice skater being pushed by two others shown in the figure. A F Ftot F1 Free-body diagram F2 F1 (a) Find the direction (in degrees) and magnitude (in N) of Ftot, the total force exerted on her by the others, given that the magnitudes F1 and F2 are 24.4 N and 17.4 N, respectively. direction 35.4 (counterclockwise from the direction of F1 is positive) magnitude 30 N (b) What is her initial acceleration (in m/s²) if she is initially stationary and wearing steel-bladed skates that point in the direction of Ftot? (Assume the value of μs for steel on ice is 0.04. x (c) What is her acceleration (in m/s²) assuming she is already moving in the direction of Ftot? Remember that friction is always in the opposite direction of motion or attempted motion between surfaces in contact. 0.27 m/s² (in the direction of Ftot)

Q5) The output $y(t)$ of a causal LTI system is related to the input $x(t)$ by the equation $\frac{dy(t)}{dt} + 10y(t) = \int_{-\infty}^{+\infty} x(\tau)z(t - \tau)d\tau - x(t)$, (4) where $z(t) = e^{-t}u(t) + 3\delta(t)$. (a) Find the frequency response $H(j\omega) = Y(j\omega)/X(j\omega)$ of this system. (b) Determine the impulse response of the system.
