Fed [463]

Answer:

48.4 km, 34.3° north of east

Explanation:

Let's say east is the +x direction and north is the +y direction.

Adding up the x components of the vectors:

x = 20 cos 60 + 30 + 0

x = 40 km

Adding up the y components of the vectors:

y = 20 sin 60 + 0 + 10

y = 27.3 km

The magnitude of the displacement is:

d = √(x² + y²)

d = 48.4 km

The direction is:

θ = atan(y/x)

θ = 34.3° north of east

A roller coaster has a 100.0 kg cart at the top of a 22.0 m ramp. As it goes down the ramp, it change 800.0 joules of energy to

AlekseyPX

Answer:

d.20760 J

Explanation:

We are given that

Mass of cart=m=100 kg

At the top,h=22 m

Amount of energy convert into heat due to friction=E=800 J

We have to find the kinetic energy at the bottom of the ramp.

Potential energy drop=mgh= $100\times 9.8\times 22=21560 J$

Kinetic energy at the bottom=Potential energy drop-energy lost due to friction

Kinetic energy at the bottom =(21560-800) J

Kinetic energy at the bottom=20760 J

Hence, the kinetic energy at the bottom of the ramp=20760 J

d.20760 J
