If Angular displacement θ = `a` t3 + `b` t2 – `c` t + `d` then find the Angular velocity (ω) at `t` sec.

Question :  Use Impulse Momentum theorem for following problem.  A car  traveling at `v` m/s collides with a wall. The impact causes the rider, who weighs `w` N, to come to a stop. The car is equipped with an advanced safety system that includes an airbag and protective gear, which slow the rider’s velocity and allow them to come to a stop in about `t` seconds. The average force experienced by the rider during the collision with the airbag and protective gear will be ……..N.  `put your anser upto four decimal place`.             

The fictional compound Covidium (molar mass = 131.8 g/mol) has a normal boiling point of 150.6°C and a normal melting point of 66.7°C.  The specific heats of Covidium (l) and Covidium (g) are 6.72 and 3.32 J/g-°C, respectively.  The heat of vaporization for the compound is 62.4 kJ/mol. The heat of fusion for the compound is 31.8 kJ/mol. Calculate the heat required to convert 42.0 g of Covidium from a gas at 180.0°C to a liquid at 92.0°C. Please submit your numerical answer, in kJ, below. Once complete, upload your calculations/work to the Quiz 1: Heating Curves assignment.
