The takeoff speed of a jetliner is 100 m/s. If the jetliner is to take off from a runway of a length of 2100 m. What must be its acceleration?
1) A car is traveling at a steady 77km/h in a 50 km/h zone. A police motorcycle takes off at the instant the car passes it, accelerating at a steady 7.3m/s2 . a)How much time elapses before the motorcycle is moving as fast as the car? b)How far is the motorcycle from the car when it reaches this speed? 2)A gannet is a seabird that fishes by diving from a great height. If a gannet hits the water at 32m/s...
A ball is thrown upward from the top of a building with a speed of 30 m/sec. The height of the building is unknown. Assume the acceleration due to gravity is 10 m/see?. 1. (2pts) Find the velocity of the ball -)as a function of timet. (Hint: a- du/dt- 10) 2. (2pts) When does the ball reach the highest point? 3. (2pts) Find the displacement traveled by the ball during 0 Sts5 4. (4pts) Find the total distance traveled by...

Cheetahs can accelerate to a speed of 19.8 m/s in 2.65 s and can continue to accelerate to reach a top speed of 28.8 m/s. Assume the acceleration is constant until the top speed is reached and is zero thereafter. Let the +x direction point in the direction the cheetah runs. Express the cheetah's top speed Vop in miles per hour (mi/h) mi/h Starting from a crouched position, how much time tae does it take a cheetah to reach its...
A stone thrown downward with an initial velocity of 34.3 m/sec travel a distance of s meters, where:s(t)=4.9t + 34.3t and t is in seconds. If a stone is thrown downward at 34.3m/sec from a height of 294 m, how long will it take the stone to reach the ground?I am putting 294 in for t and trying to solve it that way. Is this correct? If not please let know where I am going wrong.

1. A jet plane has a takeoff speed of ? = 75 m/s and can move along the runway at an average acceleration of 1.3 m/s2. If the length of the runway is 2.5 km, will the plane be able to use this runway safely? Defend your answer. 2. A person takes a trip, driving with a constant speed of 89.5 km/h, except for a 22.0 min rest stop. If the person’s average speed is 77.8 km/h, (a) how much...
