a 1600 kg car on flat ground is moving 6.25 m/s. its engine creates 1150 N forward force as the car moves 45.8 m. what is it fin
Sveta_85 [38]

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.

An airplane travels at 950 km/h. how long does it take to travel 1.00 km
Reptile [31]
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:

D = v *t

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
