1. A force of 99N is applied to a 26kg lawnmower at an downward angle of 25 degrees relative to the horizontal. There is essentially no friction due to the wheels. Find the acceleration in the x direction
2. A 6 gram bullet is accelerated from rest to a speed of 261 m/s as it travels 79 cm in a gun barrel. Assuming the acceleration to be constant how large was the acceleting force
3. A 15kg box sits on a level table and a force of 83N is applied downward at an angle of 21 degrees related to the horizontal. If the coefficient of friction is 0.4 find the acceleration in the x direction
4. A 5kg blocks sits on a level table and a string runs over the edge of the table on a pulley to a mass of 6kg. Find the acceleration of the system if the coefficient of friction is 0.1
