Initially, block A has a speed of 3 m/s as shown in the figure below. Use the principle of linear impulse and momentum to determine the speed of block B at t=6 s. The coefficient of kinetic friction between block A and the surface is HK-0.15 The pulleys are weightless and frictionless. 10 kg A 30° V4.1 = 3 m/s G- B 20 kg

In a dance jump, the dancer lifts their center of mass 40 cm.  When they land, they bend their knees as they slow to a stop and their center of mass lowers by 7.0 cm in 50 ms.  The dancer’s mass is 60 kg. (a) What is the impulse on their body as they land? (b) What is the average force on the dancer’s body? {3360 N}

A ball of mass 0.160 kg is dropped from rest from a height of 1.25 m. It rebounds from the floor to reach a height of 0.650 m. What impulse was given to the ball by the floor? magnitude  kg · m/s direction  ---Select--- upward downward

A model rocket is constructed with a motor that can provide a total impulse of 26.0 N-s. The mass of the rocket is 0.117 kg. What is the speed that this rocket achieves when it is launched from rest? Neglect the effects of gravity and air resistance. Number i Units

"A 1-kg car travelling at 30 m/s decelerates coming to stop in 5 seconds, as a result of applying the break. What is the impulse experienced by the car?" 6000 Ns 18000 NS 12000 Ns 24000 Ns None of these

In a ballistic pendulum experiment, a small marble is fired into a cup attached to the end of a pendulum. If the mass of the marble is 0.0285 kg and the mass of the pendulum is 0.250 kg, how high h will the pendulum swing if the marble has an initial speed of 5.85 m/s? Assume that the mass of the pendulum is concentrated at its end so that linear momentum is conserved during this collision. h = m

If the impulse acting on a moving 100 kg object is zero, what does that mean about the velocity of the object? Recall that impulse is: F*t = m*Δv where Δv = vf - vi     vf > vi     vf = vi     vf < vi     Not enough information to determine.

A 0.730-kg projectile travels with a velocity or magnitude 66 km/h. What is the bullets linear momentum

A cart filled with sand rolls at a speed of vcart = 1.4 m/s along a horizontal path without friction. A ball of mass m = 2.6 kg is thrown with a horizontal velocity of vball = 9.8 m/s toward the cart as shown in the figure below. The ball gets stuck in the sand. What is the velocity of the cart after the ball strikes it? The mass of the cart is 14 kg. (Assume the positive xdirection is to the right. Express your answer in vector form.) ?m/s
