To provide the pulse of energy needed for an intense bass, some car stereo systems add capacitors. One system uses a 1.6FF capacitor charged to 24 VV, double the normal 12 VV provided by the car's battery. How much energy does the capacitor store at 12 V? How much energy does the capacitor store at 24 V?

What is the average speed of a car that travels 40mph for 1 hour and 60 mph in another hour will mark brainliest

An open cart is moving along a straight frictionless horizontal track. when rain starts falling vertically into the cart, what happens to the speed of the cart?

Afaulty model rocket moves in the xy-plane (the positive y direction is vertically upward). the rocket's acceleration has components ax(t) = ? t2 and ay(t) = ? ? ? t, where ? = 2.50 m/s4 , ? = 9.00 m/s2 , and ? = 1.40 m/s3 . at t = 0 the rocket is at the origin and has velocity ~v0 = v0x ? i + v0y ? j with v0x = 1.00 m/s and v0y = 7.00 m/s. (a) calculate the velocity and position vectors as functions of time. (b) what is the maximum height reached by the rocket? (c) sketch the path of the rocket. (d) what is the horizontal displacement of the rocket when it returns to y = 0?
