Answer:
600
Explanation:
60 mph × 10 hours = 600 miles
Answer:
Explanation:
The formula to find average acceleration is a=Δv/Δt.
Convert 216 km/hr to m/s
216 km/hr * 1000 m/km * 1 hr/60 mins * 1 min/60 secs = 60 m/s
So a= (60 m/s)/(5.0*10^-3) = 12000 m/s^2
Put that into scientific notation to get 1.2*10^4 m/s^2
Answer:
Part of that kinetic energy created by moving of particles in object is transformed to heat that can be measured by thermometer.
Explanation:
By moving object creates kinematic energy, that is true. In object itself small particles are moving and creating kinetic energy as well. Part of that kinetic energy created by moving of particles in object is transformed to heat that can be measured by thermometer.
Same thing is that when you run or exercise your body temperature is raising(because of moving ).
When you sit your body does not raise temperature.
This item is solved through the concept of the conservation of momentum which states that the momentum before and after collision should be equal.
momentum = mass x velocity
(1,600 kg)(16 m/s) + (1.0x10^3 kg)(10 m/s) = (1600 + 1000 kg)(x)
The value of x is 13.69 m/s. Thus, their final speed is approximately letter D. 14 m/s.
It would decrease, hope it helps
