Q. The Apollo Lunar Module was used to create the transition from the spacecraft to the moon's surface and back. Consider the similar module for landing on the surface of Mars. Use conservation of mechanical energy to answer these questions.
(a) As lander is descending, if the pilot decides to shut down the engine when the lander is at a height of 3.0 m, (this might not be a safe height to shut down the engine) and the velocity of the lander (relative to the surface of the planet) is 1.3 m/s what will be velocity of lander at impact? Note: g on the surface of mars is about 0.4 times that on the surface of the Earth. (b) In the case of the lunar module an impact velocity of 3.0 m/s or less was essential for a safe landing. Assume this to be the case for the Mars lander as well, at what most height could the pilot shut down the engines to ensure a safe landing. Assume the velocity v0 at the time the engine is shut down is 1.3 m/s.
A bus makes a trip according to the position time graph shown in the drawing. Find the average velocity (magnitude & direction) of the bus during each of the segments labelled A, B, & C?

Before throwing a 1.49 kg discus, an athlete rotates it along a circular path of radius 1.18 m. The maximum speed of the discus is 25.7 m/s.
The parallel metal plate of a capacitor is separated by a distance of 0.5cm and is connected to a 90v battery. Discover an electric field between them and the surface charge density .
A ranger in a national park is driving at 44 km/h when a deer jumps onto the road 70 m ahead of the vehicle. After a reaction time of t s, the ranger applies the brakes to produce an acceleration of -3.00 m/s2.
Two identical carts travel at 1m/s in opposite directions on a common horizontal surface. They collide head-on and are reported to rebound, each with the speed of 2m/s.
A 0.120 kg block on a horizontal frictionless surface is attached to the spring whose force constant is 572 N/m. The block is pulled from its equilibrium position at x = 0 m to a displacement x = +0.080 m and is released from rest. The block after th..
A rocket blasts off vertically from rest on the launch pad with an upward acceleration of 2.30. At 10.0 after blastoff, the engines suddenly fail, which means that force they produce instantly stops.
