What would be the mass of an object that is moving at 5 m/s, with a total momentum of 1500 kg*m/s southeast?
1 answer:
Answer:
The mass of the object is 300 kg
Explanation:
The given parameters are;
The velocity of the object = 5 m/s southeast
The total momentum of the object = 1500 kg·m/s
The equation for linear momentum, is given as follows;
Momentum = Mass × Velocity
Therefore, the mass of the object can be found as follows;
Therefore, we have;
The mass of the object = 300 kg.

relation between linear velocity and angular velocity is given as
here
v = linear speed
R = radius
= angular speed
now plug in all data in the equation
so rotating speed is 60.9 rad/s
Answer:
The magnitude of change in momentum is (2mv).
Explanation:
The momentum of an object is given by the product of mass and velocity with which it is moving.
Let the mass of ball is m. A tennis player smashes a ball of mass m horizontally at a vertical wall. The ball rebounds at the same speed v with which it struck the wall.
Initial speed of the ball is v and final speed, when it rebounds, is (-v). The change in momentum is given by :
p = final momentum - initial momentum
So, the magnitude of change in momentum is (2mv).
