An astronaut weighs 760. N on Earth, what is his mass iCalculate the momentum of a high-speed "bullet train" with a mass of 8.9 X 10^8 kg moving at a speed of 72 m/s going North. Express your answer in standard form. n kg?

The linear momentum of an object is given by:

p = m wherever is the mass v is the velocity

Explanation:

hope this helps

positive reinforcement? ?

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
