Answer: The momentum is 0 kg*m/s.
Explanation:
The momentum formula is p = mv.
Plug in the values you know for mass and velocity.
p = (15000 kg)(0m/s)
p = 0 kg*m/s
Answer:
2.5 m/s²
Explanation:
Acceleration: This can be defined as the rate of change of velocity.
The S.I unit of acceleration is m/s²
For circular motion, the expression for acceleration is given as,
a = ω²r ................ Equation 1
Where a = acceleration of the particle, ω = angular speed of the particle, r = radius of the circular path.
Given: ω = 5 rev/s = 31.42 rad/s, r = 0.10 m.
Substitute into equation 1
a = 5²(0.10)
a = 25(0.10)
a = 2.5 m/s²
Hence the acceleration of the particle = 2.5 m/s²
Hence, none of the option is correct

Answer: - 0.75 m
Explanation: The displacement will be the sum of the slope of the graph within the given time. From time 8s to 16s, the slope m will be; Slope = (15 - 6) / (16 - 8) Slope = 9 / 8 From time 16s to 24s Slope = (15 - 0) / ( 16 - 2 Slope = -15 / 8 Displacement = 9/8 - 15/8 Displacement = -6/8
Displacement = - 0.75 m
