Acceleration
=the change in velocity per unit time....
1.
A net force of 10n is applied to a 5 kg mass. By how much does the body accelerate?
Given: F = 10n; M = 5kg
Required: A
Solution
F= ma
A= f/m
= 10 N/ 5kg
= 10 k - m/s 2 / 5 k
=2 m/s 2
(Divide the 10 to 5 and the answer is 2 m/s 2)
2. What jet force is needed to accelerate a 10- kg object by 3 m/s 2?
Given: m= 10kg ; a= 3m/s
Required= F
Solution:
F = ma
= (10kg) (30 m/s2)
= 30 kg - m/s2
=30 N
