Question

The velocity of an object is given by:

\[ v(t) = 4t - 3t^2 \]

Where \( v \) is in m/s and \( t \) is in seconds.

**If the object is at \( x = 0 \) when \( t = 0 \), where is it at \( t = 2 \) s?**

Express your answer in meters.

1. For this series of 3 questions, a jet bike is moving along a straight road with the speed described by the v-s function v(s) = 2. s2/3, (v in [m/s] and sin [m]). Your final goal is to determine the velocity (v) at a specified time. But before that, you need to answer some other questions. 3) determine the velocity (v) when the time t = 7.1 s. Your answer must include 2 places after the decimal point, and the proper unit. Your Answer: Answer units
3:04 7 This question is a long free-response question. Show your work for each part of the question. Cylindrical Object Incline Figure 1 A cylindrical object can roll down an incline, as shown in Figure 1. The incline is slightly less than one meter in length. A group of students wants to determine the acceleration of the object while it is rolling down the incline. The students have access to the following equipment. · A stopwatch, which can measure time intervals up to 999 s with a precision of 0.01 s · A clock, which can measure time intervals up to 12 hours with a precision of 1 min ute (60 s) • A meterstick, which can measure lengths up to 1 m with a precision of 1 mm · A pair of calipers, which can measure lengths up to 10 cm with a precision of 0.05 mm (a) Assume the object moves with a constant acceleration as it rolls down the incline. Write an equation that includes acceleration and quantities that can be measured or obtained from measurements by using the available equipment…

. I am planning to perform some volume-flow rate measurements in the Fluid Mechanics Laboratory. For this, I need a volumetric measuring tank (graduated cylinder) and a stopwatch. I considered the volume of the measured tank as 15 gallons and a stopwatch with reaction time as 1/10th of a second (though resolution of 1/1000th of a second). What is the volume flow rate if it takes 5 minutes to fill a 15-gallon of tank? Determine the smallest division to be on the tank in order to estimate the volume flow rate within an accuracy of ± 0.05 gpm.
PLEASE: Can you write out the answers. Typing it out doesn't make sense all together
