The guy below is wrong!
F=ma
Where force = mass x acceleration
We dont have acceleration, a= change in velocity divided by the time taken.
a = v (final velocity) - u (initial) / t
a us 8-0 (at rest means u was 0) / 20 = 0.4
Using F=ma
F= mass x acceleration
F= 4 x 0.4
F=1.6 N
Answer:
The forces offset to produce a net force of 8 N
since the ball is 1 kg
F = ma
a = f/m = 8 N/1 kg = 8 (kg m)/(s^2 kg) = 8 m/s^2
Answer:
Explanation:
The system ball-pin is modelled by the Principle of Moment Conservation:
The velocity of the bowling ball after the collision is:
all the allials must be aligned in the same direction
magnets are affected by heat, drops, and improper storage
"These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean watergets very cold, forming sea ice." this is what I found...
