Assume that an MX missile goes from rest to a suborbital velocity of 3.50 km/s in 60.0 s (the actual speed and time are classified). What is its average acceleration in m/s2? What is its average acceleration in multiples of g?

A hot air balloon is moving vertically upwards at a constant rate of 9.0 m/s. As the balloon rises, a package is dropped from the balloon and it takes 5 s to hit the ground. How far did the package fall?   Make sure to include a diagram of the physical situation, label know and unknown quantities with units, coordinate system. Please use grade 12 kinematics and label the variables as v1, v2, a (Acceleration), t (time), d (displacement) Thanks!

The velocity and acceleration of an object at a certain instant are 3 = (3.0 m/s)j ä = (5 m/s²)î At this instant, the object is Ospeeding up and moving in a straight line. speeding up and following a curved path. slowing down and following a curved path. moving with constant speed and following a curved path. slowing down and moving in a straight line.

A jet fighter needs to be at the speed of 170mi/hr. What is the acceleration needed for the jet fighter to fly off the carrier in m/s²? A carrier runway is 300ft long. Assume that the aircraft experience uniform acceleration. How long will the jet fighter need to reach the needed speed in seconds

A particle moves so that its position (in meters) as a function of time (in seconds) is r = î + 5t2 j + 5t k. (Use the following as necessary: t.) (a) Write an expression for its velocity as a function of time. V = m/s (b) Write an expression for its acceleration as a function of time. a = m/s?

Hello. I am working on a problem with motion. The questions asks me to calculate the maximum height (h1),  total time (t2), and speed of a ball right before it hits the ground. The question states that A person is throwing a ball upward into the air with an initial speed Vo = 10m/s. Assume that the instant when the ball is released, the person's hand is at a height ho = 1.5m. The speed of the ball at its peak height is zero, and the question needs to be solved in ascending part and descending part. I don't understand how to solve for the maximum height. What is the correct formula to use and why? For other questions like this, I will be able to solve them if I know the formulas for the ascending of the ball and the descent of the ball as well as the explanation. Thank you. For the sake of the question, the ball is being thrown straight up.

Imagine you are in charge of figuring out the maximum speed of a very foggy road. Consider a road that we cannot see anything beyond 15 meters. Suppose that human reaction time is 0.3s and the deceleration from pressing the brake is -10m/s². What should be the speed limit for this road in [m/s]? Hint: during the reaction time, the car still moves with constant speed. The car starts slowing down when the brake is pressed.

The acceleration of a particle is given by a = 3t - 32, where a is in meters per second squared and t is in seconds. Determine the velocity and displacement as functions of time. The initial displacement at t = 0 is so = -4 m, and the initial velocity is vo= 7 m/s. After you have the general expressions, evaluate these expressions at the indicated times. Answers: At t = 1.2 s, At t = 13.7 s, S= S = i -14.6 i -1.59 m, V = m, V = i i 5.56 240. m/s m/s

Assume that you are driving a car at 10.0 km/h and then you accelerate to 80.0 km/h with an acceleration of 3.50 m/s². How much time will it take until you reach the velocity 80.0 km/h? (Provide you answer in s with two decimal places.) Your Answer:
