A body moves in a circle of radius 0.5 m with angular velocity 4 rad s-1. Its linear speed is:

Answer: 2 m s -1.

A 1 m s-1
B 2 m s-1
C 4 m s-1
D 8 m s-1

Correct answer: B. 2 m s-1

Explanation: Linear speed v = rω = 0.5 × 4 = 2 m s-1.

Projectile trajectories launched at 15, 30, 45, 60, 75 and 90 degrees at the same speed, each annotated with range R, maximum height H and time of flight T, with coloured dots marking equal time intervals

Projectiles at equal speed: range is maximum at 45°, and complementary angles (30° and 60°) share the same range. Image: Cmglee, CC BY-SA 3.0, via Wikimedia Commons.
