An object experiences a change of momentum of 54 kg • m/s in 9s. What is the force causing this change

At 45 degrees a ball will bounce off of a wall... Question 1: What would the x component of the ball's change in momentum be, answer in kg m/s. Question 2: What would the y component of the ball's change in momentum be, answer in kg m/s Question 3: When the ball makes contact with the wall for 0.02 seconds, what would the magnitude of the force that the ball exerts on the wall, answer in N

The electron mass is 9 × 10-31 kg. What is the momentum of an electron traveling at a velocity of (0, 0, -2.4 × 108) m/s? kg • m/s p = What is the magnitude of the momentum of the electron? p = Additional Materials Your answer cannot be understood or graded. More Information kg. m/s

A 6.2 kg object is initially moving to the left at 10.8 m/s. A constant force is applied to the object over 1.29 seconds and the object ends up moving at 5.9 m/s to the left.What was the change in momentum experienced by the object? ____________kgm/sWhat was the size and direction of the force applied over the 1.29 seconds? Newtons
