Answer:

vf=94.4 m/s

Explanation:

acceleration is the final velocity minus initial velocity divided by time

a = (vf-vi)/t

Given:

a= 14.2 m/s^2

vi= 0 (at rest)

t = 6.6

Solve for vf

a = (vf-vi)/t

a*t=vf-vi

(14.2)*(6.6)=vf - 0

vf=94.4 m/s

An object moves 360 km in 2 hours calculate its speed into km/h and m/s

erik [133]

Explanation:

Speed= Distance / time

Speed= 360/2

= 180 km/h

Speed= 180 × 5/18

= 50 m/s

What is the physical meaning of the physics equation of a spring force vs displacement graph?

Vilka [71]

Explanation:

The force of a spring is described by Hooke's law:

F = kx

where k is the spring stiffness in N/m, and x is the displacement in m.

A spring force vs displacement graph is a line passing through the origin with a slope of k.

A car is moving at a constant speed of 14 m/s when the driver presses down on the gas pedal and accelerates for 14 s with an acc

Vinil7 [7]

acceleration of car is 1.8 m/s^2

time = 14 s

initial speed = 14 m/s

so the final speed is calculated by

$v_f = v_i + at$

$v_f = 14 + 14 * 1.8$

$v_f = 39.2 m/s$

so the total distance moved in this interval of time is

$d = \frac{v_f + v_i}{2}* t$

$d = \frac{39.2 + 14}{2}* 14$

$d = 372.4 m$

now the average speed is given as

$v = \frac{d}{t}$

$v = \frac{372.4}{14}$

$v = 26.6 m/s$

so the average speed will be 26.6 m/s
