11. Momentum & Impulse

A baseball is thrown with a velocity of $25m/s$ and has a momentum of $10\mathrm{kg}\cdot m/s$. What is the mass of the baseball?

Which of the following objects has the largest momentum relative to Earth's surface?

What is the momentum of a $50$-kilogram ice skater gliding across the ice at a speed of $5$ m/s?

Which of the following objects has the largest momentum if all are moving at the same speed of $10m/s$?

For a particle of mass $m$ moving with velocity $v$, what is the magnitude of its momentum $\left|p\right|$?

$When\; a\; constant\; force\; acts\; on\; an\; object,\; what\; does\; the\; object\text{'}s\; change\; in\mathrm{momentum}depend\; upon?$

A 60 g tennis ball with an initial speed of 32 m/s hits a wall and rebounds with the same speed. FIGURE P11.40 shows the force of the wall on the ball during the collision. What is the value of F_max , the maximum value of the contact force during the collision?

A 500 g particle has velocity v_x = −5.0 m/s at t = −2 s. Force F_x = (4−t²) N, where t is in s, is exerted on the particle between t = −2 s and t = 2 s. This force increases from 0 N at t = −2 s to 4 N at t = 0 s and then back to 0 N at t = 2 s. What is the particle's velocity at t = 2s?

FIGURE EX11.6 is an incomplete momentum bar chart for a collision that lasts 10 ms. What are the magnitude and direction of the average collision force exerted on the object?

Which of the following statements best explains the relationship between the force acting on a vehicle and its momentum, assuming the mass is constant and the force is applied over a certain time interval?

A slowly moving ship can have a greater momentum than a fast-moving racing car when _______.

In a closed system where two objects collide and stick together, how much total $p$ (momentum) does the system have immediately after the collision?
