Answer:
The distance the piece travel in horizontally axis is
L=3.55m
Explanation:
Now the angular velocity is the blade speed so:
assuming no air friction effects affect blade piece:
time for blade piece to fall to floor
Now is the same time the piece travel horizontally
blade piece travels HORIZONTALLY = (24.5)(0.397) = 9.73 m ANS
Answer:
So Tammy must move with speed 4.76 m/s in opposite direction of Jackson
Explanation:
As per law of conservation of momentum we know that there is no external force on it
So here we can say that initial momentum of the system must be equal to the final momentum of the system
now we have
final they both comes to rest so here we can say that final momentum must be zero
now we have
Answer:
A = 1.4 m/s²
B = -0.10493 m/s³
a = 1.29507 m/s²
T = 28095.8271 N
T = 1.13198 W
Explanation:
t = Time taken
g = Acceleration due to gravity = 9.81 m/s²
The equation
Differentiating with respect to time
At t = 0
Hence, A = 1.4 m/s²
B = -0.10493 m/s³
At t = 5 seconds
a = 1.29507 m/s²
T = 28095.8271 N
Weight of rocket
T = 1.13198 W
