A car traveled 60km in 45 min.What is the cars average speed in km/hr

Physics
1 answer:
sergey [27]3 years ago
5 0

Given that,

Distance = 60 km

Time = 45 min

To find,

The average speed of the car.

Solution,

Average speed of an object is equal to the total distance divided by total time taken.

45 min = 0.75 hour

It can be given as :

V=\dfrac{60\ km}{0.75\ h}\\\\=80\ km/h

Therefore, the average speed of the car is 80 km/hr.

If the speed of an object were to triple, what would be the increase of kinetic energy? KE2 = _____ KE1
Olin [163]
Kinetic energy is directly proportional to the square of their velocities... so if velocity has been increased 3 times, increase in K.E would be: 3^2 = 9

In short, Your Answer would be: KE2 = 9 * KE1

Hope this helps!
