To calculate speed the formula is D/T=S
You can substitute Distance for position since it's labeling the position it's reached from its initial start.
To find average you take all your values, add them up, and divide by how many values there are.
1.2/0.024=50
2.8/0.051=54.9 (we'll round it up to 55)
4.2/0.084=50
16.34/2.34= 6.98 (we'll round it to a 7)
50+55+50+7=162
162/4=40.5
So her average speed was 40.5 Km/h.
The internal energy of the
system is characterized by the equation U = Q + W where U is the internal
energy, Q is the heat and W is work. You are given 2,380 J of energy to do work
as 12,900 J of heat so add up. The internal energy is 15,280J.
Explanation:
simple machine can multiplayer of speed and force
Answer: 0.687 m/s
Explanation:
Given
Mass of object, m = 76.7 g = 0.767 kg
Force constant of the spring, k = 3.34 N/m
Amplitude of the spring, x = 38 cm = 0.38 m
EPE(i) = KE(f) + EPE(f)
1/2kx(i)² = 1/2mv² + 1/2kx(f)²
1/2 * 3.34 * 0.38² = (1/2 * 0.767 * v²) + [1/2 * 3.34 * (0.38/2)²]
1/2 * 3.34 * 0.1444 = (1/2 * 0.767v²) + 1/2 * 3.34 * 0.0361
1/2 * 0.482 = 1/2 * 0.767v² + 1/2 * 0.121
0.241 = 1/2 * 0.767v² + 0.06
1/2 * 0.767v² = 0.181
0.767v² = 0.181 * 2
0.767v² = 0.362
v² = 0.362 / 0.767
v² = 0.472
v = √0.472
v = 0.687 m/s
Answer:
Time = 0.187 secs
Explanation:
Parameters given:
Speed of hot air balloon = 1.60 m/s
Speed of toss = 10.7 m/s
Distance between passenger and friend at time of toss = 2m
To find the time given, we can simply divide the distance between the passenger and her friend by the speed of the toss. Mathematically,
Time = distance/speed
Time = 2/10.7
Time = 0.187 secs
Therefore, it takes 0.187 seconds for the camera to get to her.
