Car 1 has a mass of 65000 kg and moves at a veloctiy of 0.80 m/s. Car 2 with a mass of 92000 kg and a velocity of 1.2 m/s, overtakes Car 1 and couples to it. Neglecting friction, find the common velocity of the two cars after they become coupled.

Which is the best for showing percentages of different types of cars sold(gas hybrid , electric , other ) in the united states ?

What is meant by the statement" the melting poin of glycerine is 13 degree celsius

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s
