Typically no. Displacement can be in multiple directions as a vector. of something is traveling only along x, then it would be true though this is usually not the case.

Displacement is the distance and direction from the start point to the end point.

If the motion starts and stops on the x-axis, then the displacement is equal to delta-x toward either the left or the right. But that would be rare and unusual.

You are taking care of two small children, Sarah and Rachel, who are twins. On a nice cool, clear day you decide to take them ro
BlackZzzverrR [31]

Answer:

Explanation:

Rachel and Sarah are standing on horizontal ground . Let T₁ be the tension between Rachel and Sarah and Sarah is in between you.

Force = mass x acceleration

Apply this equation on Rachel

T₁ = 23 x 2 = 46 N

Let T₂ be tension between Sarah and me and it is inclined at 60°

Force = mass x acceleration

Apply this equation on Sarah

T₂ cos 60 - T₁ = 23 X 2 = 46

T₂ cos 60 - 46 =46

T₂ cos 60  = 92

T₂ = 92 / .5

= 184 N

In a little league baseball game, the 145 g ball enters the strike zone with a speed of 14.0m/s . the batter hits the ball, and
Novosadov [1.4K]

Answer:

5365 N

Explanation:

v = Final velocity = 23 m/s

u = Initial velocity = -14 m/s (opposite direction)

m = Mass of ball = 145 g

t = Time taken = 1 ms

Impulse is given by

J=m(v-u)

Impulse is also given by

J=Ft

Ft=m(v-u)\\\Rightarrow F=\dfrac{m(v-u)}{t}\\\Rightarrow F=\dfrac{0.145\times (23-(-14))}{1\times 10^{-3}}\\\Rightarrow F=5365\ N

The magnitude of the average force exerted by the bat on the ball is 5365 N

The mass of a satellite in geostationary orbit is 1,847 kg. The mass of Earth is 5.97*1024 kg. Because of the force Earth exerts
ozzi

Answer:

411.88 N

Explanation:

Given that:

mass of satellite m = 1847 kg

mass of the earth M = 5.97 × 10²⁴ kg

centripetal acceleration a = 0.223 m/s²

The magnitude of the force exerted by the earth on the satellite = the centripetal force that is being exerted by the satellite.

∴

m \dfrac{v^2}{r} = G \dfrac{mM}{r^2}

ma = G \dfrac{mM}{r^2}

G \dfrac{mM}{r^2}= 1847 \times 0.223

G \dfrac{mM}{r^2}= 411.88 \ N
