A trolley cart of mass 1.0kg is moving on a flat horizontal surface at a constant velocity of 2.0m/s. A force of 3.0N is applied to the trolley in the opposite direction to its motion for a time of 1.5s and then the force is removed. What is the magnitude of the final momentum of the trolley?

A constant net force of 10.3 N directed in the x-direction is exerted on a 2.7 kg object for a time of 1.66 s. What is the object's change in momentum during this time? Assume proper SI Units

A 0.145 kg ball is thrown horizontally into a wall, to the right, with an initial velocity of 8.0 m/s and bounces in the opposite direction with a velocity of 5.0 m/s. Find the change in momentum of the ball. -2.78 kg m/s O-1.90 kg m/s 1.90 kg m/s 0.44 kg m/s

As shown in the figure below, cars #1 and #2 are sliding across a horizontal frictionless surface. The cars are equipped with a coupling arrangement similar to the one on railroad cars. Car #1 overtakes car #2 and they have a totally inelastic collision and become coupled together. You know the mass of each car; m₁ = 12.0 kg and m₂ 41.0 kg. In addition, you are provided with the following graph, which shows the momentum of car #1 before, during and after the collision. p (kg-m/s) 100 40 Determine the velocity (in m/s) of car #2 before the collision. m/s t (s)

A ball weighing 10 kg is initially at rest, then suddenly explodes into 3 pieces. The picture shows the length and direction for each one of the three velocities. What were the length and direct of the ball before the explosion? Hint : use the momentum conservation principle on the y axis and x axis.

Object 1 has a mass m1 and a velocity v⃗ 1v→1 = (2.40 m/sm/s )x^. Object 2 has a mass m2 and a velocity v⃗ 2v→2 = (3.20 m/sm/s )y^. The total momentum of these two objects has a magnitude of 17.0 kg⋅m/s and points in a direction 66.0 ∘ above the positive x axis.  Find m1.

Two carts mounted on an air track are moving toward one another. Cart 1 has a speed of 0.8 m/s and a mass of 0.35 kg. Cart 2 has a mass of 0.71 kg. (a) If the total momentum of the system is to be zero, what is the initial speed of Cart 2 in meters per second? m/s Enter a number. (b) Does it follow that the kinetic energy of the system is also zero since the momentum of the system is zero? Yes No (c) Determine the system's kinetic energy in joules in order to substantiate your answer to part (b). Can you write an expression for the total kinetic energy of the system (both carts)? J

A space probe is traveling in outer space with a momentum that has a magnitude of 3.04 x 107 kg·m/s. A retrorocket is fired to slow down the probe. It applies a force to the probe that has a magnitude of 1.19 x 106 N and a direction opposite to the probe's motion. It fires for a period of 8.86 s. Determine the momentum of the probe after the retrorocket ceases to fire.

If a rainstorm drops 1 cm of rain over an area of 10 km² in the period of 1 hour, what is the momentum of the rain that falls in one second? Assume the terminal velocity of a raindrop is 10 m/s.
