By collapsing and crumpling, the force and energy is absorbed by the crumple zone and it is not transferred to the passengers inside. This is a safety feature for the passengers.
1. To solve this problem you can use the formula:
Force = mass × acceleration
16 = 5 × a
16/5 = a
3.2 m/sec^2 = acceleration
2. To solve this formula use the same formula that was given above:
F = ma
F= 1239 kg × 4m/sec
F = 4956 N
3. To solve this problem use the formula:
Weight = mass × gravity
W = 35 × 9.8
W = 343 N
4. To solve this problem use the formula:
Momentum = mass × velocity
M = 95 kg × 8 m/s
M = 760 kg × m/sec
hope this helps :)
Answer:
B) Adding many new features to the model makes it more likely to over fit the training set.
Explanation:
Increasing number of features without increasing the amount of training data, increase over fitting in the model because features may be irrelevant and increase the redundant information in the model.
Answer:
Explanation:
0°Κ = -273.15°C = -459.67 °F
1 °K = 9/5 °F
a) 75.6 - 273.15 = -197.55 °C
b) -459.67 + 75.6(9/5) = -323.59 °F
Answer:
the final speed of the barrier would be 40m/s
Explanation:
Hello, I think I can help you with this.
the momentum is given by:
P=m*v, where P is the momentum, m is the mass of the object and v is the speed of the object.
if the momentum is transferred completely it means that the barrier will have the same amount of momentum, in other terms
momentum of the moped=momentum of the barrier
mass of the moped*speed of the moped=*speed of the barrier
let's isolate the final speed of the barrier
final speed of the barrier is
so, the speed is 40 m/s
