How does mass effect the speed of a forced object

Answers

Answer 1

Answer:

Answer:

the bigger the mass, the smaller the acceleration and the smaller speed

Explanation:

this can be proven from the formula F = ma

F = m×speed/time

Or a practical example is that of a heavy object and a light object if pushed with the same force, it'll be observed that the small object moves faster or with a greater speed than the heavy object

A rural mail carrier logged the mileage on the odometer at the start of the mail route as 31,500 miles. After 6.5 hours, the carrier returned the truck and recorded the mileage at 31,713 miles. What was the average velocity of the mail truck? Explain your reasoning.

Answers

Answer: $32.77\ mi/hr$

Explanation:

Given

Initially Reading on the odometer is $31,500\ miles$

Final reading on the odometer is $31,713\ miles$

Time taken is $t=6.5\ hr$

average velocity $=\frac{\text{Displacement}}{\text{time}}$

$v_(avg)=(31713-31500)/(6.5)$

$v_(avg)=(213)/(6.5)$

$v_(avg)=32.77\ mi/hr$

Thus the average velocity of mail truck is $32.77\ mi/hr$

If a turtle walks at a constant speed of 0.23 m/s, how long will it take to cover a distance of 65 meters?

Answers

Time = (distance) / (speed)

Time = (65 meters) / (0.23 m /s)

Time = (65 / 0.23) sec

Time = 282.6 seconds ( that's 4 minutes 42.6 seconds)

Final answer:

The time it would take a turtle moving with a speed of 0.23 m/s to cover a distance of 65 meters is approximately 282.61 seconds.

Explanation:

The subject of this question is physics, specifically the concept of speed, distance, and time. The formula that relates these three quantities is speed = distance/time.

In this case, we are asked to calculate the time it would take for a turtle moving with a constant speed to cover a certain distance. Here, the given speed (0.23 m/s) of the turtle and the distance it needs to cover (65 meters) are known.

By rearranging the formula to solve for time, we get time = distance / speed. Plugging in the values, we get time = 65 meters / 0.23 m/s. Doing the math gives approximately 282.61 seconds. Thus, it would take the turtle around 283 seconds to cover the distance of 65 meters at a speed of 0.23 m/s.
