The mass of a stroller and the child it carries is 23.7 kg. A man pushes the stroller with a force of 142 N at an angle of 38.0°
to the vertical. The stroller experiences a friction force of 24.0 N due to the brake accidentally being on. What is the stroller's acceleration forward? A. 5.99 m/s2
B. 3.90 m/s2
C. 2.68 m/s2
D. 4.98 m/s2
The horizontal resultant force applied is 142*Cos(38) which is <span>135.62N
24N of opposing force therefore the total force acting on the stroller is 135.62-24=</span><span>111.62N
applying the formula f=ma where f is force m= mass a= acceleration plugging the values we get </span>the stroller's acceleration forward as <span>3.90 m/s^2</span><span>
