A 5.75 x 10-kg rocket takes off from the moon where the acceleration due to gravity is 1.60 m/s2 by exhausting 5.00 kg of gas per second at a speed of 2.20 x 1o m/s. Determine the acceleration of the rocket.

A 1.5 kg object B is hanging by a string. An object A with a mass of 30 grams penetrated in the object B and they both rise to a 0.15 m height. What was the initial velocity of the object A just before it strikes the object B?

A 20 g ball of clay travelling east at 2.0 m/s collides with a 30 g ball of clay travelling 30° south of west at 1.0 m/s. What are the speed and direction of the resulting 50 g blob of clay? O 0.41 m/s, 41° south of east O 0.58 m/s, 47° South of east O 0.58 m/s, 41° south of east O 1.83 m/s, 12.8° north of east O 1.83 m/s, 12.89 south of east O 0.41 m/s, 47° south of east

A 1000kg car is traveling 20m/s to the right when it collides head-on with a 1700kg pickup truck traveling 16m/s to the left. The vehicles lock together inelastically following the collision, which lasts 0.4s. What direction did the vehicles move after the collision? Car (initial) Truck (initial) Combined (final) Car only (final) Truck only (final) How fast were the vehicles moving after the collision? unit What was the magnitude of the impulse? unit What was the magnitude of the impact force? unit |pl unit |||

1.) A van travels at a speed of 120 km/h along a highway. The mass of a spare tire in the cabin is 12.9 kg. Determine the KE of the spare tire.

Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, the first having a mass of 180,000 kg and a velocity of 0.300 m/s,and the second having a mass of 95,000 kg and a velocity of −0.120 m/s. (The minus indicates direction of motion.) What is their final velocity (in m/s)? m/s

Bob and Tom take a sled weighing 10 N to a frozen pond. The sled is initially at rest on the ice. Bob who weighs 490 N runs at 2 metres per second and jumps on the sled. A few seconds later, Tom who weighs 540N runs at 4 metres per second and jumps on the sled with Bob. Keep all values to 3 decimal places. A)What is the velocity of the sled after Bob jumps on to it? B)What is the velocity of the sled after Tom jumps on it?

What is the acceleration of a 5000-kg rocket taking off from the Moon, where the acceleration due to gravity is only 1.6m/s2, if the rocket expels 8.00 kg of gas per second at an exhaust velocity of 2.20×103m/s?

What is the acceleration of a 5000 kg rocket taking off from the Moon, where the acceleration due to gravity is only 1.6 m/s^2 if the rocket expels 8.00 kg of propellant per second at an exhaust velocity of 2.20 × 10^3 m/s?

a 3kg red car travelling to the right at 5 m/s strikes a stationary 2kg blue car, locking the two of them together. what is the final velocity of the two cars?
