It depends on what f, m and a are.
Even if they are force, mass and acceleration, the fact that no units are given means that it is impossible to give an answer.
if the question were 15 M of F then answer is 15 Minutes of Fame which was a quote from Andy Warhol
Baron F. M. Koenig Warthausen died on 1986-12-15.
15 minutes of fame per person
a = v/t F= m*a -> a = F/m v/t =F/m -> F=mv/t Now it depends on how long the collision lasts
F = M a 15 = M (1.5) M = 15 / 1.5 = 10 kilograms
15% of 52= 15% * 52= 0.15 * 52= 7.8
What you mean to say is: "The net force acting on the ball is 30 N."F = M AA = F / M = (30) / (4) = 7.5 m/s2
0.4m = 52 Therefore, m = 52/0.4 = 130 Therefore, m = 130
15% of 52= 15% * 52= 0.15 * 52= 7.8
15 f = 4.572 m, 12 f = 3.657 ==> 16.72 m2
F = M AA = F/M = (450)/(30) = 15 meters/sec2
52°C is 126°F -your welcome
