If the mass of the object is doubled and the speed is halved then kinetic energy will change by a factor of:
madam [21]

Answer:

kinetic energy will change by a factor of 1/2

Option C) 1/2 is the correct answer

Explanation:

Given the data in the question;

we know that;

Kinetic energy = 1/2.mv²

given that mass of the object is doubled; m1 = 2m

speed is halved; v1 = V/2

Now, New kinetic energy will be; 1/2.m1v1²

we substitute

Kinetic Energy = 1/2 × 2m × (v/2)²

Kinetic Energy = 1/2 × 2m × (v²/4)

Kinetic Energy = 1/2 × m × (v²/2)

Kinetic Energy = 1/2 [ 1/2mv² ]

Kinetic Energy = 1/2 [ KE ]

Therefore; kinetic energy will change by a factor of 1/2

Option C) 1/2 is the correct answer

A group of bike riders took a 4 hour trip. During the first 3 hours, they traveled a total of 50 km, but
zlopas [31]

Answer:

15km/hr

Explanation:

The average speed for the entire trip is the sum of the total distance traveled divided by the total time of the trip.

Total time  = 4hr

distance for the first 3hrs  = 50km

distance for the last 1hr  = 10km

  Total distance  = 50km + 10km  = 60km

Now;

  Average speed  = \frac{total distance }{time taken}  

 Insert the parameters and solve;

 Average speed  = \frac{60km}{4hr}   = 15km/hr

A baseball player throws 4 balls every 20 seconds. what is his throw frequency
frosja888 [35]

Answer:

Frequency, f = 0.2 Hz

Explanation:

We have,

A baseball player throws 4 balls every 20 seconds.

It is required to find the frequency of the baseball.

Frequency of an object is defined as the number of times an event occurs. It is given by number of throws per unit time. It can be given by :

f=\dfrac{4}{20}\\\\f=0.2\ Hz

So, the frequency of his throw is 0.2 Hz.

During spring semester at MIT, residents of the parallel buildings of the East Campus dorms battle one another with large catapu
natali 33 [55]

Answer:

110.7 J

Explanation:

Hooke's law is represented by the formula:

F = ke  where F is the force in Newton, K is force constant and e is extension in m

work done = 1/2ke² = 1/2 K ( e² - e₀²) and e₀ is the extension at relaxed length

e₀ =0

work done = 0.5 × 82N/m × (2.70 m)² = 110.7 J
