A 60 kg rower is paddling a 30 kg canoe with a 2 kg paddle at a constant speed of + 10 m/s. If she loses her grip on the paddle and it flies backward with a velocity of - 20 m/s, what is the final momentum of the boat and rower?

A bug flies at a velocity of 0.75 m/s into an oncoming breeze blowing at 0.25 m/s. What is the resultant velocity of the bug? A 0.0 M/S B0/25 M/S C 0.50 M/S D 1.0 M/S

A car is moving with a velocity (3.0 m/s) € x ˆ + (1.0 m/s) € y ˆ and 3.0 seconds later its velocity is (6.0 m/s) € x ˆ - (3.0 m/s) € y ˆ. What is the direction of the average acceleration of the car?

When water vapor condenses on the inside of a window, the window becomes

Try this out. Use a calculator! We can use the formula KE=0.5m*V^2. To find the kinetic energy (KE) of a payload of mass (m) 100 kg as it flies through the air at the velocity (v) of 55 m/s. (Multiply 0.5 x the mass x velocity squared.
