Answer from: nofer

Its velocity as well as acceleration are both non-zero.

This seems to be attributable to the reality that towards the maximum height, just the vertical dimension of that though velocity approaches zero. These same horizontal parts are already in play. As a result, the velocity would be non-zero.Gravity's acceleration would operate upon that ball, hence the acceleration will then be non-zero.

As a result, the aforementioned response is correct.

Answer from: aiken11192006

Correct Choice: c)

Explanation:

When an object is launched with an angle with respect to the horizontal, it describes a curved path exclusively under the action of gravity.

The velocity at any point of the path has two components:

The horizontal component has a constant value because no acceleration acts in that direction.

The vertical component has a variable value that depends on the acceleration of gravity and the time.

When the golfer drives the golf ball in a high arcing shot it reaches a maximum height and then returns to the ground.

a) The velocity is never zero until the ball hits the ground. The acceleration is never zero. False

b) The x-velocity is constant and equal to the horizontal component of the initial velocity. The y-velocity is zero at the highest point. Only one condition is true, thus the whole statement is False.

c) The x-velocity is never zero, and the y-velocity is zero as explained above. True

d) The velocity is non-zero, and the acceleration is not zero. False

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm. the wire diameter is d = 0.9 mm. the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2) in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?
