MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A body of mass 4.3 kg is moving along the x-axis with an initial speed of 2.4 m/s when it is acted upon by three constant forces at the instant represented below. (Express your answers in vector form. Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) F 1 37 Fa F, = 70.0 N F, = 30.0 N F. = 80.0 N (a) What is the acceleration of the body (in m/s2)? a m/s (b) What is the body's velocity (in m/s) 16.6 s later? m/s (c) What is its displacement (in m) after 16.6 s?

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A bullet shot from a rifle has mass of 10.0 g and travels to the right at 415 m/s. It strikes a target, a large bag of sand, penetrating it a distance of 45.0 cm. Find the magnitude (in N) and direction of the retarding force that slows and stops the bullet. (Assume the positive direction is to the right. Indicate the direction with the sign of your answer.)
