A block with mass m1 hangs from a rope that is extended over an ideal pulley and attached to a second block with mass m2 that sits on a ledge slanted at an angle of 20 (Fig. P5.49).

Squids are the fastest marine invertebrates, using a powerful set of muscles to take in and then eject water in a form of jet propulsion that can propel them to speeds of over 11.5 m/s. What speed (in m/s) would a stationary 1.40 kg squid achieve by ejecting 0.110 kg of water (not included in the squid's mass) at 3.75 m/s? Neglect other forces, including the drag force on the squid. m/
••An air-track cart of mass m1 = 0.14 kg is moving with a speedv0 = 1.3 m>s to the right when it collides with a cart of massm2 = 0.25 kg that is at rest.

Two blocks are attached by massless strings and accelerated to the right on a frictionless horizontal surface by TB. The masses are m1 = 2.0 kg and m2 = 3.0 kg. The acceleration of the block 1 is 5.0 m/s2. Match the answers with questions.
In a soccer match against Mexico in 2014, US Women’s National Team striker Alex Morgan scored a sweetheaded goal in the 79th minute of the game. Just as the ball left her head, the horizontal component of its acceleration was 225 m/s , and the vertical component of its acceleration was -200 m/s (assuming thepositive direction points up). If the ball has a mass of 425 g, what was the magnitude and direction of theforce she applied to the ball? Note- you can ignore the weight of the ball.
