Shown here is an odd pyramid. Find the angle

If we add vector to vector  the resultant vector is longer than both  and

A ball is dropped from a height = [h] m on a frictionless loop-de-loop of radius . What is the largest radius the loop can have so that the ball makes it around without losing contact with the track? Please give your answer in units of m.

A projectile is fired at a speed of = [v] m/s and at an angle

Starting from one oasis, a camel walks 30 km in a direction 40° south of west and then walks 25 km toward the north to a second oasis. What is the direction from the first oasis to the second oasis?

The three blocks shown are released from rest and are observed to move with accelerations that have a magnitude of 1.2 m/s2. What is the magnitude of the friction force on the block that slides horizontally? Disregard any pulley mass or friction in the pulley and let M = 3.0 kg.

When a cart of mass has a force applied to it for a distance , it will attain a velocity of . If instead a force of is applied for a distance to a cart of mass , what velocity will it have?

Shown here is a plot of velocity as a function of time. Over what range of times do we see the greatest positive displacement?
