An eletrostatic paint sprayer consists of a charged metal sphere. Charged paint droplets (the sign the same as the metal sphere) are shot towards the metal sphere using a paint gun. The paint droplets repel and move towards a grounded object that needs to be painted. In the figure below, an electrostatic paint sprayer has a 0.25 m diameter metal sphere at a potential Vsphere of 23 kV that repels paint droplets onto a grounded wall.  a) What charge is on the sphere? b)    What charge must a 0.14 mg drop of paint have to arrive at the object with a speed of 12 ms?

See figure. All charges are positive except q3. What is the initial acceleration of q4, which has a mass of 6.50 micrograms? Recall that acceleration is a vector and should be expressed accordingly.

A 9230-kg truck collides head on with a 1250-kg parked car. The vehicles entangle together and slide a linear distance of 10.6 meters before coming to rest. Assuming a uniform coefficient of friction of 0.820 between the road surface and the vehicles, determine the pre-collision speed of the truck.
