1) A car with an initial velocity of 10.8 km/h experiences an acceleration of - 0.82 m/s2 for 2.0 s.
(a) Calculate the car’s final speed.
(b) What is the car’s displacement?

2)A plane traveling at – 45 m/s slows down to – 15 m/s in a time of 8.0 s.
(a) What was the planes displacement during this
time?
(c) What was the plane’s acceleration during this time?

I need help asap ;-_(

Debbie places two shopping carts in a cart corral she pushes the first cart which then pushes a second cart what force is being exerted

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
