An electron has an initial velocity of 6.00 ✕ 106 m/s in a uniform 1.00 ✕ 105 n/c strength electric field. the field accelerates the electron in the direction opposite to its initial velocity.
(b) how far does the electron travel before coming to rest?
m
(c) how long does it take the electron to come to rest?
s
(d) what is the electron's speed when it returns to its starting point?
m/s

In a good thermo flask the main cause of heat loss is

The friction of the water on a boat produces an acceleration of -10. m/s2. if the boat is traveling at 30. m/s and the motor is shut off, how long it take the boat to slow down to 5.0 m/s?

The second largest public utility in the nation is the sole provider of electricity in 32 counties of southern florida. to meet the monthly demand for electricity in these counties, which is given by the inverse demand function p = 1,200 – 4q, the utility company has set up two electric generating facilities: q1 kilowatts are produced at facility 1, and q2 kilowatts are produced at facility 2 (so q = q1 + q2). the costs of producing electricity at each facility are given by c1(q1) = 8,000 + 6q12 and c2(q2) = 6,000 + 3q22, respectively. determine the profit-maximizing amounts of electricity to produce at the two facilities, the optimal price, and the utility company’s profit
