Recently, the Amazon and Virgin groups launched commercial space flights. These flights do not store fuel on board, instead, they inhale oxygen from the air. If the weight of one of these new rockets is 2420 kN, while a regular rocket is 19579 kN, what would be the acceleration of these two rockets close to the Earth's surface when a thrust of 25467 kN is applied?

Mary applies a force of 78 N to push a box with an acceleration of 0.49 m/s2. When she increases the pushing force to 86 N, the box's acceleration changes to 0.73 m/s2. There is a constant friction force present between the floor and the box. (a) What is the mass of the box in kilograms?  kg (b) What is the coefficient of kinetic friction between the floor and the box?

Before they were decommissioned, the NASA space shuttles required two solid rocket boosters (SRBs) to launch the shuttle from Earth’s surface. Both SRBs produced 1.7 x10^7 N at liftoff. The combined mass of a shuttle and rocket boosters was about 1.5 x 10^6 kg. (5 marks) (a) Calculate the net acceleration of a space shuttle and rockets at the time of liftoff. (b) Calculate the speed of the shuttle and rockets after 10.0 s

A 1.90 kg box is moving to the right with speed 9.00 m/s on a horizontal, frictionless surface. At t = 0 a horizontal force is applied to the box. The force is directed to the left and has magnitude F(t)=( 6.00 N/s^2 )t2 If the force continues to be applied, what is the velocity of the box at 3.50 s?

An astronaut (70.0 kg) is on a 15,000 kg rocket. It takes off from the launchpad onEarth, with the engines providing 200,000 N of thrust.What is the astronaut’s apparent weight as it is taking off?

Mary applies a force of 71 N to push a box with an acceleration of 0.41 m/s². When she increases the pushing force to 76 N, the box's acceleration changes to 0.65 m/s². There is a constant friction force present between the floor and the box. (a) What is the mass of the box in kilograms? kg (b) What is the coefficient of kinetic friction between the floor and the box?

A clever coyote uses rocket powered skates to try to catch a roadrunner. The mass of the coyote is 38.1 kg. If the coyote starts from rest, and accelerates to a final speed of 26 m/s in a distance of 2.4 m, how much thrust force did the rockets excert to get him to his final speed? Assume this thrust is constant over the 2.4 m.

the position of a 2-kg mass is given by x=2t^3-2t^2+5t. What is the net force on the mass at t=0 and t=1? (use m/s^2)

A 0.55 kg football is thrown with a velocity of 17 m/s to the right. A stationary receiver catches the ball and brings it to rest in 0.021 s. What is the force exerted on the receiver?Answer in units of N.
