I have these two problems that I have been given. I know that they need me to do something with Newtons second and third laws but I just cant figure out how. Can you please help me? A block with mass mp = 8.25 kg is suspended on a string. You pull upwards on the string creating a tension force of magnitude Ty, = 84.9325 N.If the upward speed of the block is 4.25 m/s right now, then what is its speed 2.5 s later?Don't know where to start?A Hint About SpeedVf = Two ice skaters are skating toward one another and accidentally collide. One of the ice skaters is a parent with a mass of 135 kg. The other skater is a small child whose mass is only 22 kg. Before thecollision, both skaters have a speed of 3.9 m/s. When they collide, the parent picks up the child, and their final speed is 2.613 m/s, in the direction the parent was moving. The magnitude of the force that theparent exerts on the child at the instant they collide is 839 N. What is the magnitude of the force that the child exerts on the parent at that instant?A Hint About N3LAnother HintFep =

According to Bartleby Guidelines, I am going to answer only one question, kindly ask another…

In a tug of war with a toy between Joe and Fred, Joe pulls the toy with a force equal to 25N. Fred pulls the toy in the opposite direction at 35N. The acceleration of the toy is 5m/s^2. What is the mass of the toy?
I have a question for elevator problems: Newton's law states that there is always an equal and opposite force. But for elevator problems, if it accelerates upwards... we say that the normal force is greater than the gravitational force. So is Newton's third law still applied here and if so how? Because technically the opposite force is not equal in magnitude for it to be able to accelerate
Help Please! Thanks! The weight of a person on earth is equal to 302 N. Suppose this person is on our moon where the acceleration due to gravity is -1.6 m/s2. What is their weight on the moon in Newtons?What is their mass on the moon in kg?
A flea jumps by exerting a force of 1.12 x 10-5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 1.12 x 10-6 N on the flea. Find the direction and magnitude (in m/s2) of the acceleration of the flea if its mass is Fwind points to the right. We will consider this to be the +x direction and vertical to be the ty 6.0 x 10-7 kg. (Let us assume me that F direction.) magnitude direction Additi m/s² O (measured clockwise from the vertical)
Newton's 2nd Law can be symbolized as EF = ma Let mass A = 100 kg Let mass B = 1 kg What is true about an object of large mass versus an object of small mass? The more massive object has more inertia. The objects have the same inertia. The more massive object has less inertia. The objects have the same weight near Earth's surface. The more massive object has a larger weight near Earth's surface. V If the same net force is applied to both then the larger mass has the larger acceleration. O If the same net force is applied to both then the objects will haye the same acceleration. O If the same net force is applied to both then the larger mass has the smaller acceleration.
A small 1600 kg rocket applies its thrusters from rest to generate a net force of F=1600t+2990 newtons, where tt is time. Assuming no air resistance, calculate the rocket's velocity, v, in m/s after 8 seconds. Enter your answer for v in m/s, correct to three significant figures: ....... m/s
A 60 kg skydiver falls, beginning at rest. This isn't an ordinary skydive though, because it's taking place on an alien planet where g = 8 m/s2. The drag force on the skydiver is given by FD = -0.14 v (N). Calculate the speed of the skydiver after they have fallen for 322 s, in m/s. (Please answer to the fourth decimal place - i.e 14.3225)
Hi, I need help with part d of this question. Thanks.
If you are floating in outer space, and you need to change your motion in order to get back to the safety of your spaceship. You throw your shoe away with a force of 320 Newtons, which means the shoe pushes back on you with a force of 320 Newtons. If you have a mass of 61 kg, what is the magnitude of your acceleration?
In an experiment performed in a space station, a force of 60N causes an object to have an acceleration equal to 4 m / s^2. what is the objects mass?
I am a little confused on Newtons Seconds Law in Two dimensions. I know that when acceleration is zero that the net force in both the x and y-directions becomes zero. Is that because when acceleration is zero there's no net force?
