In the figure here, a red car and a green car move toward each other in adjacent lanes and parallel to an x axis. At time t = 0, the red car is at xr = 0 and the green car is at xg = 221 m. If the red car has a constant velocity of 29.0 km/h, the cars pass each other at x = 43.0 m. On the other hand, if the red car has a constant velocity of 58.0 km/h, they pass each other at x = 76.9 m. What are (a) the initial velocity (in km/h) and (b) the (constant) acceleration (in m/s2) of the green car? Include the signs. Please type answer no write by hend.
An inquisitive physics student and mountain climber climbs a 51.0-m-high cliff that overhangs a calm pool of water. He throws two stones vertically downward, 1.00 s apart, and observes that they cause a single splash. The first stone has an initial speed of 2.06 m/s. (b) What initial velocity must the second stone have if the two stones are to hit the water simultaneously?
Let SA = 15t2 + 10t + 20 and SB = 5t2 + 40t, t greater than or equal to 0, be the position of cars A and B, respectively, that are moving along parallel straight lanes of a highway, t in minutes and s in inches). How far is A ahead of car B when t is 0? At what instant of time do they have the same velocity.which car is ahead at that instant
A red car and a green car, identical except for the colour, move toward each other in adjacent lanes and parallel to an x-axis. At time t = 0, the red car is at Xr = 0 and the green car is at Xg = 220 m. If the red car has a constant velocity of 20 km/h, the cars pass each other at x = 44.5 m, and if it has a constant velocity of 40 km/h, they pass each other at x = 76.6 m. What are (a) the initial velocity and (b) the constant acceleration of the green car?
Answer the ff: 1. A juggler throws a bowling pin straight up with an initialspeed of 8.20 m/s. How much time elapses until the bowling pinreturns to the juggler’s hand? 2. A car travels in the +x-direction on a straight and levelroad. For the first 4.00 s of its motion, the average velocity of thecar is vav-x = 6.25 m/s. How far does the car travel in 4.00 s?
The figure shows the unusal path of a confused football player. After receiving a kickoff at his own goal, he runs downfield to within inches of a touchdown, when reverses direction and races back until he's tackled at the exact location where he first caught the ball. During this run, which took 25s what is (a) the path length he travels (b) his displacement (c) his average velocity in the x-direction and (d) his average speed?

A red car and a green car identical except for the color, move toward each other in adjacent lanes and parallel to an x-axis. At time t=0, the red car is at Xr = 0 and the green car is at Xg =220 m. If the red car has a constant velocity of 20km/hr, the cars pass each other at x=44.5 m, and if it has a constant velocity of 40km/hr, they will pass each other at x =76.6 m. a). Determine the time(s) associated with the motion of the red car. EV b). derive the appropriate equations for the green car. APc). What is i. the initial velocity of the green car? AN ii.

A group of students celebrate their first year of medical school with a hot-air balloon ride, which is rising upward with a constant speed of 3.0 m/s. When the balloon is 3.50 m above the ground, one of the students who is taking a selfie with the other students accidentally drops her smart phone over the side of the balloon (fortunately with a OtterBox case). With what speed would the phone hit the ground in m/s? Note that the displacement of the phone dropping 3.50 m would be - 3.50 m. For the same situation as Question 9, how long in seconds would the smart phone be in the air before it hits the ground?
