+ -11 points SerPSET9 4.P.013.MI. My Notes + Ask Your Teacher In a local bar, a customer slides an empty beer mug down the counter for a refill. The height of the counter is 1.18 m. The mug slides off the counter and strikes the floor 0.60 m from the base of the counter. (a) With what velocity did the mug leave the counter? m/s (b) What was the direction of the mug's velocity just before it hit the floor? (below the horizontal) 4. + -/1 points SerPSET9 4.P.007. The vector position of a particle varies in time according to the expression " = 5.00 î - 5.4042 where ř is in meters and t is in seconds. (a) Find an expression for the velocity of the particle as a function of time. (Use any variable or symbol stated above as necessary.) m/s (b) Determine the acceleration of the particle as a function of time. (Use any variable or symbol stated above as necessary.) aa m/s2 (c) Calculate the particle's position and velocity at t = 3.00 s. F= m m/s 3. + -12 points SerPSET9 4.P.006. A particle initially located at the origin has an acceleration of ã = 1.009 m/s2 and an initial velocity of 7; = 7.00î m/s. (a) Find the vector position of the particle at any time t (where t is measured in seconds). ( tî + Z î) m (b) Find the velocity of the particle at any time t. ( + tî) m/s (c) Find the coordinates of the particle at t = 1.00 s. X = m y = m (d) Find the speed of the particle at t = 1.00 s. m/s 1. + -/1 points SerPSET9 4.P.001. My Notes + Ask Your Teacher A motorist drives south at 24.0 m/s for 3.00 min, then turns west and travels at 25.0 m/s for 3.00 min, and finally travels northwest at 30.0 m/s for 1.00 min. For this 7.00 min trip, find the following values. Let the positive x axis point east. (a) total vector displacement m (magnitude) south of west (b) average speed m/s (c) average velocity m/s (magnitude) o south of west 2. + -/1 points SerPSET9 4.P.002. My Notes + Ask Your Teacher When the Sun is directly overhead, a hawk dives toward the ground with a constant velocity of 5.65 m/s at 63.0° below the horizontal. Calculate the speed of its shadow on the level ground. m/s
