LEARNING TASK 2: Problem solving on acceleration (20 points)
1. Johnson's car accelerates from 0 m/s to 60 m/s northward in 15 seconds. What is the acceleration of the
car?
2. Calculate the acceleration of Ruby riding her bicycle in a straight line that speeds up from 4 m/s to 6
m/s in 5 seconds?
3. A car traveling initially at 20 m/s is accelerated to 40 m/s in 10 seconds. What is the acceleration of the
car?
4. Ariel dropped a golf ball from her second story window. The ball starts from rest and hits the sidewalk 1.5
seconds later with a velocity of 14.7 m/s. Find the average acceleration of the golf ball.
5. A car moving with 20 m/s uniformly slows its velocity. It comes to a complete stop in 10 seconds. What is
its acceleration? (Ang sagot dito ay dapat negative kasi ito ay isang example ng deceleration or
negative acceleration kagaya ng example sa problem number 2 sa lecture ng acceleration)​
