A0.0950-kg ball is thrown at 28.0 m/s toward a brick wall. 1) determine the impulse that the wall imparts to the ball when it hits and rebounds at 28.0 m/s in the opposite direction. the positive direction is toward the wall. (express your answer to three significant figures). kg⋅mskg⋅ms submit you currently have 0 submissions for this question. only 5 submission are allowed. you can make 5 more submissions for this question. 2) determine the impulse that the wall imparts to the ball when it hits and rebounds at an angle of 45.0∘∘. the positive direction is toward the wall. (express your answer to three significant figures). kg⋅mskg⋅ms submit you currently have 0 submissions for this question. only 5 submission are allowed. you can make 5 more submissions for this question. 3) if the ball thrown in part (b) contacts the wall for 0.0100 s, determine the magnitude and direction of the force that the wall exerts on the ball. the positive direction is toward the wall. (express your answer to three significant figures).
