When the velocity of an object is constant, there is no acceleration . Acceleration is defined as a change in velocity over time.
Problem three wants to know if velocity and acceleration have the same signs. I'll assume that on the x-axis the kick goes to the right, that means that velocity has a positive direction therefore positive, acceleration however, is slowing down therefore negative, this is commonly mistaken as deceleration but it's just negative acceleration.
 4. when there's constant acceleration, velocity is changing all the time
(constant acceleration would be seen as a parabolic motion where velocity is seen changing at every point.)
you can use the four kinematic equations to find several things like time, distance, and acceleration for the rest

Typical Pressurized Water Reactors can produce 1100 to 1500
lozanna [386]

Answer: about 1,100,000,000 to 1,500,000,000 Joules/second

Explanation:

1 MW (megawatt) = 1,000,000.00 J/s (joules per second)

1100(1,000,000) = 1,100,000,000

1500(1,000,000) = 1,500,000,000

faust18 [17]

Complete Question:

In the same configuration of the previous problem 3, four long straight wires are perpendicular to the page, and their cross sections form a square of edge length a = 13.5 cm. Each wire carries 7.50 A, and the currents are out of the page in wires 1 and 4 and into the page in wires 2 and 3.

a) Draw a diagram in a (x,y) plane of the four wires with wire 4 perpendicular to the origin. Indicate the current's directions.

b) Draw a diagram of all magnetic fields produced at the position of wire 3 by the other three currents.

c) Draw a diagram of all magnetic forces produced at the position of wire 3 by the other three currents.

d) What are magnitude and direction of the net magnetic force per meter of wire length on wire 3?

Answer:

force, 1.318 ₓ 10⁻⁴

direction, 18.435°
