It is 2058 and you are taking your grandchildren to Mars. At an elevation of 41.5 km above the surface of Mars, your spacecraft is dropping vertically at a speed of 277 m/s. The spacecraft is to make a soft landing -- that is, at the instant it reaches the surface of Mars, its velocity is zero. Assume the spacecraft undergoes constant acceleration from the elevation of 41.5 km until it reaches the surface of Mars. How much time will it take the spacecraft to reach the surface of Mars from the elevation of 41.5 km?

An object is thrown vertically upward from the surface of Mars, where the acceleration due to gravity is ?1=3.70 m/s2.g1=3.70 m/s2. The initial velocity is ?1,v1, and the object reaches a maximum height of ?1.y1. What is the maximum height, ?2,y2, if the object is thrown with a speed of ?2=1.15?1v2=1.15v1 from the surface of Saturn's moon Rhea? The acceleration due to gravity on Rhea is ?2=0.264 m/s2.g2=0.264 m/s2. Give your answer as a multiple of ?1.

a) Your cosmic journey brought you into the vicinity of a neutron star. In fact, you are orbiting this neutron star at an orbital distance of 2,184 kilometers. The neutron star has mass of 1.6 solar masses (MSun = 1.99 × 1030 kg). What is the local acceleration due to gravity that you experience in your spaceship? Express your answer in m/s2; use scientific notation and round the coefficient to two decimals. b) What is the escape velocity from Earth’s...

Speed means the absolute value of the velocity, hence it is always non-negative. While the sign of the velocity indicates the direction of the motion, the speed is insensitive to the direction. For example, speed is the value displayed by car’s speedometer; it does not indicate the direction of driving (e.g., northbound versus southbound). At time t = 0 seconds (s) an object has zero velocity and it starts a free fall from the altitude of 1200 metres (m) above...

You throw a ball vertically upward with an initial velocity of 10 m/s from a window located 20 m above the ground. Knowing that the acceleration of the ball is constant and equal to 9.81 m/s^2 downward (this makes for negative acceleration as upward motion is positive and downward motion is negative and gravity pulls downward), determine: (a) The acceleration at t = 2 s (b) The equation for velocity (Because you are looking for an equation for velocity, you...

Question: You stand at the bottom of a long ramp (i.e. one used for wheelchair access) and throw a tennis ball towards the top of the ramp, as shown in the sketch. Assume that the tennis ball leaves your hands a height h = 1.800 m from the ground and at a speed of v0 = 14.00 m/s and an angle of elevation of 51.03°, as shown in the sketch. Take the origin of a Cartesian coordinate system on the...

Pretend you are a technical advisor to a film shoot in a spy movie. You have to determine the motion of a get-away car so that it arrives in front of a casino exactlyat the moment James Bond comes out of the front door. The scene will be shot from above (from a helicopter) so the motion of the car from where it is initially parked tothe casino will be shot as one scene. To ensure that the car appears...

A jet accelerates at a=3.92 m/s^2 from rest until it reaches its takeoff velocity of 360 km/hr. It has to travel for 5 seconds at its takeoff velocity before taking off. What's the minimum distance that the jet will travel on the runway? A car backs up at a constant speed for a short time, then applies the brakes and steadily comes to rest. Sketch velocity-time and position-time graphs that depict the car's motion. Assume that the forward direction is...
