1. The unknown is acceleration
2. The givens are the force(28,913N) and the mass(2350kg)
3. The equation is a=f/m where a is acceleration,f is force and m is mass
4.a=28913/2350 a=12.30340426
5. Therefore its acceleration is 12.30m/s²(rounded to nearest hundredth)
Answer:
the sample is approximately 4065 years old
Answer:
x = ½ aw t²
x = d − ½ az t²
Explanation:
The position of each car at time t is:
x = x₀ + v₀ t + ½ at²
For car W:
x = 0 + (0) t + ½ aw t²
x = ½ aw t²
For car Z:
x = d + (0) t + ½ (-az) t²
x = d − ½ az t²
Solving the system of equations for x will give us the location the cars meet (relative to car W's starting point).
Answer:
Summer begins in the Northern Hemisphere on June 20 or 21 when the North Pole is tilted a full 23.5° toward the sun. On this day, the Northern Hemisphere has the most hours of daylight, while the Southern Hemisphere has the least hours of daylight.
Explanation:
An average cyclist generates about 183 watts while doing 19 mph or 30.4 kph. Power = force × velocity. Force of a pedalling applied by a human for achieving 30.4 kph = 183/8.44 = 21.68 newtons. This is for upright bicycles.
