Answer:
Velocity of skater after throwing the snowball is 2.57 m/s
Explanation:
Given :
Mass of skater, M = 62.2 kg
Mass of snowball, m = 0.145 kg
Velocity of snowball relative to ground, v = 39.3 m/s
Consider v₁ be the velocity of skater after throwing the snowball.
According to the problem, initially the velocity of skater and snowball is same. So,
Velocity of skater before throwing snowball, u = 2.66 m/s
Applying conservation of momentum,
Momentum before throwing snowball = Momentum after throwing snowball
(M + m) u = Mv₁ + mv
Substitute the suitable values in the above equation.
v₁ = 2.57 m/s
a) To find the solution of this point we need to calculate the relation of the control resolution, that is,
Where
R= Range of the joint
B= Storage capacity
Making the substitution of the previous values we have,
B) For the now we need to calculate the accuracy, that is,
Where
= Standard deviation
The accuracy of the robot
Making the substitution,
c) At end we can to calculate the repeatability, that is,
Answer:
The acceleration of the car is 7.85 m/s²
Explanation:
Given;
vx(t)= (0.910m/s³)t², given time traveled by the car 't' = 5.0 s
⇒To determine the velocity for 5 seconds, we substitute in 5.0 s for t
vx(5)= (0.910m/s³)(5s)²
= (0.910m/s³)(25s²)
vx = 22.75 m/s
⇒To determine the acceleration of the car when vx=12.0m/s
Acceleration is change in velocity per unit time
when vx=12.0m/s, our new equation becomes; 12 = (0.910m/s³)t²
Solving for t: t² = 12/0.91
t² = 13.187
t = √13.187 = 3.63 s
Acceleration = Δv/Δt
Acceleration = 7.85 m/s²
Answer:
total volume is 0.9125 m³
Explanation:
given data
oil = 28 litres
pressure p = 40 MPa
final pressure p2 = 35 MPa
initial pressure p1 = 30 MPa
y = 1,4
to find out
volume of accumulator
solution
so we here say that volume of oil
v3 - v2 = 28 litres
so v3 = 0.028 + v2 ......................a
and volume formula is
v1 = v2 ...................1
so v2 = v3 ..............2
put here value in equation 2
v2 = (0.028 + v2)
v2 = 0.274 m³
and here v1 will be
v1 = 0.274
v1 = 0.3365 m³
and v3 will be
v3 = 0.028 + v2
v3 = 0.028 + 0.274
v3 = 0.302 m³
so
total volume is v1 + v2 + v3
total volume = 0.274 + 0.3365 + 0.302
total volume is 0.9125 m³
