·         N1L = "If the forces on an object are balanced (resultant force = zero) the object either:

o    continues at rest

o    continues with a constant velocity"

 

·         N2L = "If the forces on an object are unbalanced it will accelerate in the direction of the unbalanced force"

1.4 Questions on Acceleration

Tuesday, July 06, 2010

1. A car changes its velocity by 30 m/s in 5 seconds, what is the acceleration of the car?

 

2. A bike starts from rest and accelerates to 20 m/s  over a period of 6 seconds. What is the acceleration of the car?

 

3. A man moving at 2 m/s accelerates at a rate of 3 m/s2 for 2.5 seconds. What is the new velocity of the man?

 

4. A car decelerates from 60 m/s to 20 m/s at a rate of -5 m/s2. How long does this deceleration take the car?
