Seton PHYSICS Home Study School FIRST QUARTER TEST 6 (SETON GRADED) JMJ Pay for us Test 6 (Lesson 24), Form A SHOW YOUR WORK Name: 6. Erwin pushed a 0.25-kg crate across a level frictionless surface. He applied a constant horizontal force of 5.0 newtons to the right on the crate for 1 4 seconds. 5.0 N (a) Find the impulse delivered to the crate. (b) Find the magnitude of the final velocity of the crane if it was initially at rest. 7. While playing softball. Robert swings and hits the 0.35-kg ball. (a) Find the total change in momentum if the ball's initial velocity is -14/ m/s and its final velocity is +46/ m/s. (b) If the bat exerts a constant force on the ball for 0.084 s. find magnitude and dire
