Consider the function \[ f(t)=\left\{\begin{array}{ll} 0 & \text { if } 0 \leq t<4 \\ 4 & \text { if } 4 \leq t<7 \\ 0 & \text { if } 7 \leq t<\infty \end{array}\right. \] a. Use the graph of this function to write it in terms of the Heaviside function. Use \( h(t-a) \) for the Heaviside function shifted \( a \) units horizontally. \[ f(t)= \] \( \square \) help (formulas) b. Find the Laplace transform \( F(s)=\mathcal{L}\{f(t)\} \) for \( s \neq 0 \). \[ F(s)=\mathcal{L}\{f(t)\}= \] \( \square \) help (formulas)

An astronaut is on the surface of an asteroid where the acceleration due to gravity is -1 ft/sec^2. He is wearing a spacesuit which only allows him to jump 6 inches (1/2 foot) high on Earth, where acceleration due to gravity is -32 ft/sec^2. How high can he jump on the asteroid if he jumps at the same initial speed?

A block on an inclined surface is connected to another block that is hanging over the top edge of the incline, as shown in the following diagram. The blocks in the system are moving in such a way that block A (with a mass of 2 kg) is moving upwards, as block B (with a mass of 20 kg) slides down the ramp. If the coefficient of friction is 0.24 and the ramp makes an angle of 25° with the horizontal. What is the acceleration of block B? 7.0 m/s² 20 m/s² 0.94 m/s² 2.0 m/s²
