2. If a 15 kg bowling ball is thrown down the alley with a force of 60 what is the acceleration? * O 0.25 m/s2 O 4 m/s2 900 m/s2

24. A pickup truck with mass 980 kg is initially at rest. The truck accelerates to a speed of 95 km/hr within a distance of 60 meters. What the direction and size of the force that acts on the truck? a. b. If the truck were carrying a load of 200 kg, what new force would be required to achieve the same acceleration?

1. A spring scale is fastened to the ceiling of a railway car. When a 1.0-kg block is hung from the scale, it reads 12 N and is oriented as shown in the figure. What is the approximate acceleration of the car as measured by an observer at rest on the ground outside of the car? 07 m/s² to the right 7 m/s² to the left 12 m/s² to the right O 12 m/s² to the left It is impossible to calculate since the angle & has not been given.

A horizontal force of 5.0 N pushes a 0.50-kg block against a vertical wall. The block is initially at rest. If µ. – 0.60 and 0.50, the acceleration of the block is: Ⓒ4.8 m/s² Ⓒ3.8 m/s² Ⓒ 9.8 m/s² 0.0 m/s² 08.0 m/s2
