An object initially traveling in a straight line with

Physics
1 answer:
SashulF [63]3 years ago
6 0

Answer:

We conclude that the total distance traveled by the object in the 4 seconds is 36 m.

Explanation:

Given

  • Initial velocity u = 5.0 m/s
  • Acceleration a = 2.0 m/s²
  • Time t = 4 s

To determine

The total distance traveled by the object in the  4.0 seconds is

<u>Important Tip:</u>

We can determine the total distance traveled by the object in the  4.0 seconds by using the equation of motion such as

s=ut+\frac{1}{2}at^2

where

  • s = distance
  • u = initial velocity
  • a = acceleration
  • t = time

substituting u = 5.0, a = 2, and t = 4 in the formula

s=ut+\frac{1}{2}at^2

s=\left(5\right)\left(4\right)+\frac{1}{2}\left(2\right)\left(4\right)^2

s=20+16

s=36 m

Therefore, we conclude that the total distance traveled by the object in the 4 seconds is 36 m.

How much time will it take for a truck to travel 20 meters if it is traveling at 4 m/s?
ss7ja [257]

Answer:

<h2>The answer is 5 s</h2>

Explanation:

The time taken can be found by using the formula

t =  \frac{d}{v}  \\

d is the distance

v is the velocity

From the question we have

t =  \frac{20}{4}  \\

We have the final answer as

<h3>5 s</h3>

Hope this helps you

Approximately how much electrical energy does a 5-W lightbulb convert to radiant and thermal energy in one hour?​
k0ka [10]

Answer:

18,000 j

Explanation:

the lightbulb dissipates 5W of power

P = ΔE / Δt

rearrange to solve for energy

ΔE = PΔt

P = 5W

t =  1 hour = 60 minutes = 3600 seconds

ΔE = 5 * 3600

ΔE = 18000 J
