A projectile is launched at an angle of 30 degrees with an initial velocity of 20 m/s. Assuming negligible air resistance, what is the horizontal range of the projectile?

An object is moving in a circular path at a constant speed. Which of the following statements is true about its acceleration?

A particle is undergoing uniform circular motion. If the radius of the circle is doubled and the speed is halved, what happens to the centripetal acceleration?

A projectile is fired at an angle such that its horizontal range is equal to its maximum height. What is the angle of projection?

Two projectiles are launched with the same initial speed. Projectile A is launched at 30 degrees and Projectile B at 60 degrees. Which projectile will have a greater range, assuming level ground and negligible air resistance?

An object is moving in a circle with a non-constant speed. What type of acceleration does it experience?

A ball is thrown horizontally from a cliff. Ignoring air resistance, what is the shape of its trajectory?

What is the angle between the velocity and acceleration vectors at the highest point of a projectile's trajectory (ignoring air resistance)?

The angular velocity of a rotating object is given by ω(t) = 2t + 1 rad/s. What is the angular acceleration at t = 2 seconds?

A particle's position is given by r(t) = (3t^2)i + (4t)j. What is the magnitude of the particle's velocity at t = 1 second?
