For each of the following problems, give the net force on the block, and the acceleration, including units. 1) 12 N 26 N 7 kg Net Force = a F/m 2) 180 N. 3) 4) 40 kg 20 N Net Force = a= 200 N 30 N 5) 100 kg 60 N 40 kg 300 N Net Force = a= = F/m 70 N Net Force = 20 kg a= 190 N Net Force a= For problems 6-9. using the formula net Force = Mass Acceleration. calculate the net force on the object 6) a=3 m/s 9 kg F=ma= a = 40 m/s 5 kg F=ma 7) 8) a=4 m/s 9) 12 kg a = 6 m/s 200 kg F=ma F=ma 10) Challenge: A student is pushing a 50 kg cart, with a force of 600 N. Another student measures the speed of the cart, and finds that the cart is only accelerating at 3 m/s. How much friction must be acting on the cart? Hint: Draw a diagram showing the cart, and the two forces acting on it.
