Tanya [424]4 years ago
6 0

Answer:comparing the total displacement and tota distance covered by Ben Jerry.

Explanation:

Total distance travelled by both is;

m+n=z

Total displacement of both is;

x+y=z

Therefore;

comparing equation 1 and 2;

x+y=m+n

A baseball rolls along a flat parking lot in a straight line at a constant speed of 3.8 m/s. How
Studentka2010 [4]

This is a uniform rectilinear motion (MRU) exercise.

To start solving this exercise, we obtain the following data:

<h3><u>DATA:</u></h3>
  • V = 3.8 m/s
  • D = ¿?
  • T = 15 sec

To calculate the distance, multiply the speed by the time.

We apply the following formula: d = v * t

We clear our data in the formula:

\bf{d=3.8\dfrac{m}{\not{s}}*15 \not{s} }

\bf{d=57 \ m}

The baseball in 15 seconds will roll a distance of 57 meters.

What is the average speed of a train that travels at 100km/hr for 6 hours and then 120km/hr for 5 hours
Sindrei [870]

Answer:

Explanation:

Average speed = Total distance / Total time.

100 km/hr

r = 100 km / hr

t = 6 hours

d = 6 * 100 = 600 km

120 km / hr

r = 120 km / hr

t = 5 hour

d = 120 * 5

d = 600 km

Total distance = 600 + 600 = 1200 km

Total time = 5 hour + 6 hours = 11 hours.

Average speed = 1200 km / 11 hours = 109.1

A cruise ship with a mass of 1.03 ✕ 107 kg strikes a pier at a speed of 0.652 m/s. It comes to rest after traveling 4.44 m, dama
Gnoma [55]

Answer:

The average force exerted on the pier is 4.9 \times 10^{5} N

Explanation:

Given :

Mass of ship m = 1.03 \times 10^{7} Kg

Distance x = 4.44 m

Velocity v = 0.652 \frac{m}{s}

Now find the average velocity,

 v _{avg} = \frac{0+0.652}{2}

 v _{avg} = 0.326 \frac{m}{s}

Now find the time taken by ship to travel 4.44 m.

   t = \frac{x}{v_{avg} }

   t = \frac{4.44}{0.326}

   t = 13.62 sec

Now calculating average force,

  F = \frac{m \Delta v}{\Delta t}

Where \Delta v = 0.652 -0 = 0.652 \frac{m}{s}

  F = \frac{1.03 \times 10^{7} \times 0.652 }{13.62}

  F = 4.9 \times 10^{5} N

Therefore, the average force exerted on the pier is 4.9 \times 10^{5} N
