Add 10N acting left to right, to 10N acting left to right

This question is simple kinematics. If the initial velocity is 22 m/s and the ball is headed upwards we are trying to figure out time correct? so We know that when a ball reaches its maximum height it is at a velocity of 0. In this case there is no acceleration listed, so we can assume that the acting force is gravity. (- 9.81 m/s squared.) Now that we have an initial velocity, a final velocity, and an acceleration we can solve for t using the formula. v final - v initial divided by acceleration = T

let a satellite is moving in an orbit given by the equation x2+y2=4.At what rate the position of the satellite y is changing with respect to x.When the satellite is at the point (2^1/2, 2^1/2)

An object is rolled up an incline. If the object is 2.75 m up the incline after 4.50 seconds and rolling back down at a velocity of 1.90 m/s, what is the acceleration?

A rock is thrown upwards from a building 55.8m high. As the rock falls it barely missed the building and falls towards the ground in a total for 4 seconds from release. Find the initial velocity and maximum height the rock traveled.

Part 1: An airplane flies 221 km due west from city A to city B and then 387 km in the direction of 25.5 degrees north of west from city B to city C. What is the distance between city A and city C?
Answer in units of km

Part 2: Relative to city A, in what direction is city C? Answer with respect to due east, with the
counter-clockwise direction positive, within the limits of −180 degrees to +180 degrees.
Answer in units of degrees

An object (moving man) starts from rest and accelerates at a rate of 4.3 m/s^2 for 2.05 seconds. What is his displacement from the start position?

if you accelrate from rest to a rate of 6.00 m/s2 for a time of 4.10 seconds . determine displacement during the time period

ms.wolk is approaching a stoplight moving with a velocity of 30.0 m/s. the light turns yellow, and wolk applies the breaks and skids to a stop. if wolks deceleration is 8.00 m/s2, determine the displacement of the car during the skidding process.

Johnny is riding his bike down the sidewalk, at a speed of 4m/s. Sarah is jogging in the other direction, at 3m/s. What is the speed with which they will pass by each other
