The formula for finding force is F=W/d so then you plug in the numbers:
F=600/4.8
F=125N
Answer:
83,900 J
Explanation:
First, find the acceleration:
F = ma
1150 N = (1600 kg) a
a = 0.719 m/s²
Now find the final velocity.
Given:
Δx = 45.8 m
v₀ = 6.25 m/s
a = 0.719 m/s²
Find: v
v² = v₀² + 2aΔx
v² = (6.25 m/s)² + 2 (0.719 m/s²) (45.8 m)
v = 10.2 m/s
Now find the final KE:
KE = ½ mv²
KE = ½ (1600 kg) (10.2 m/s)²
KE = 83,920 J
Rounded to three significant figures, the final kinetic energy is 83,900 J.
First calculate the <em>percentage of one hr</em> it takes. You can do this by dividing the distance by the velocity. The general formula for this is:

always remember to make sure your units are the same.
so that's 1km by the 950km/h velocity.
1/950 = 0.0010526 hrs
Then multiply that answer by 3600 (<em>the number of seconds in 1 hr</em>) to find how many seconds this is.
0.0010526 * 3600 = 3.789 seconds
Answer:
They can cause sunburn. Exposure to UV rays can cause premature aging of the skin and signs of sun damage such as wrinkles, leathery skin, liver spots, actinic keratosis, and solar elastosis. UV rays can also cause eye problems.
