📝 Practice Problems

Dropping a Pebble: A student drops a pebble from the edge of a vertical cliff. The pebble hits the ground four seconds after it was dropped. What is the height of the cliff?

Kangaroo: A kangaroo is capable of jumping to a vertical height of 2.62 m. Determine the takeoff speed of the kangaroo.

Acceleration of a Dragster: A dragster accelerates to a speed of 112 m/s over a distance of 398 m. Determine the acceleration (assume uniform) of the dragster.

Velocity of a Bike: A bike is traveling at a velocity of 4 m/s to the north. The biker accelerates with an acceleration of 0.1 \(m/s^2\) to the south for five seconds. What is the final velocity of the bike?

Top Speed of a Sloth: A three-toed sloth can achieve a top speed of 0.17 mph (0.076 m/s). If we assume that a sloth can achieve this speed in 3 seconds, what is the acceleration of the sloth?
