Answer:

50N increasing

Explanation:

it looks like we want the net force. this is the sum of all forces acting on the object. here the problem is extremely simplified and we are even given the values of force. this looks like the rocket is producing an upward force of 160 newtons. it also looks like maybe weight (gravity) and drag (air resistance) are producing downward force against the rocket. we can say those would be subtracting from the amount of upwards force. so 160-40-70=50N. since the force is positive that means we will still have a magnitude of force vector that points upward and so we will increase.

While passing a slower car on the highway, you accelerate uniformly from 20.1 m/s to 33.2 m/s in a time of 10.6 s. How far do yo

BaLLatris [955]

Answer:

282 m

Explanation:

Given:

v₀ = 20.1 m/s

v = 33.2 m/s

t = 10.6 s

Find: Δx

Δx = ½ (v + v₀) t

Δx = ½ (33.2 m/s + 20.1 m/s) (10.6 s)

Δx ≈ 282 m

A man 6.00 ft tall approaches a street light 15.0 ft above the ground at the rate of 4.00 ft/s. How fast is the end of the man

klio [65]

Answer:

$\frac{dx}{dt} = 10 ft/s$

Explanation:

As per given figure let say the tip of the shadow is at distance "x" from the base of the lamp

so here we have

$\frac{x}{15} = \frac{x - y}{6}$

so we have

$6x = 15 x - 15 y$

$15 y = 9 x$

now we have

$5\frac{dy}{dt} = 2\frac{dx}{dt}$

$5(4) = 2\frac{dx}{dt}$

$\frac{dx}{dt} = 10 ft/s$

If there is a negative sign in front of the Hooke's Law equation, what does the force, F, represent?

SashulF [63]

Answer:

Hooke's law, given by $F=-kx$ is denoted with a negative sign to regard that the direction of restoring force that occurs opposite in direction of the force that caused the displacement $x$ . F represents the force required to create a spring displacement of $x$ .

Explanation:

As with many things in physics, the negative sign represents direction. In this case, after a spring is displaced a distance of $x$ from equilibrium, the restoring force created by the spring will be in opposite direction of the force applied to move the spring there, represented by F.
