Question

The only force acting on a 5kg object has components Fx = 15N and  Fy = 25N. Find the  acceleration of the object.
​

Answer 1

Answer:

acceleration, a =

m

F

=

10

25

=2.5m/s

2

Using v = u + at

we get, v - u = at (velocity gain is 10m/s, so v-u = 10)

10 = 2.5t

t = 4s

Answer 2

Answer:

Problem 2: The only force acting on a 5kg object has components Fx = 15N and Fy = 25N. Find the acceleration of the object.

Solution.

m= 5kg

Fx = 15N, Fy = 25N

F = Fxi + Fyj

= √ 225 + 625 = √850

F = ma

Or, a = F/ m = √850/5 = 5 √34/5 = √34 = 5.83m/s2
