A car travelled for a total of 10 meters as he slows down uniformly from 60 mph to 20 mph. A) What is the magnitude of his deceleration in m/s?? B) Using the deceleration, initial speed, and final speed, calculate the amount of time it took him to decelerate from 60 to 20 mph. (round all answers to 2 sig fig) (be careful for units) A man is falling from rest due to gravity. A) How far in meters can...
On the Moon, the acceleration due to gravity is 1.62 m/s2 How far would a 41 g rock fall from rest in 9.5 seconds if the only force acting on it was the gravitational force due to the Moon?
On Mars, the acceleration due to gravity is 3.71 m/s2. How far would a rock fall in [Number 6.01] s if you dropped it on Mars?
A raindrop with initial mass 'M', from rest begins to fall due to gravity. The drop gains mass due to the cloud, which is proportional to its mass and velocity: where 'k' is a constant. a) Show that the rain drops acceleration follows the case when the air resistance is given by: . b) Even though we are not assuming air resistance, what is the terminal velocity?

If a projectile is fired with an initial velocity of v0 meters per second at an angle α above the horizontal, and air resistance is assumed to be negligible, then its position after t seconds is given by the parametric equationsx=(v0 cos α) t y=(v0 sin α) t-1/2 g t2where g is the acceleration due to gravity (9.8 m / s2)(a) If a projectile is fired with α=45° and v0=900 m / s, when will it hit the ground? How...
Acceleration due to gravity on board of your spaceship that orbits Jupiter is 25.89 m/s. How high is your spaceship above Jupiter's cloud tops? Express your answer in kilometers and round it to the nearest integer. M Jupiter = 1.90 x 104 kg; R Jupiter = 69,911 km. 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 22.424 kilometers. The neutron star has mass...
2: For this problem the heights are low enough that the acceleration due to gravity can be approximated as -g. (Note: even at low Earth orbit, such as the location of the International Space Station, the acceleration due to gravity is not much smaller then g. The apparent weightlessness is due to the space station and its occupants being in free-fall.) A rocket is launched vertically from a launchpad on the surface of the Earth. The net acceleration (provided by...
If a projectile is fired with an initial velocity of vo meters per second at an angle a above the horizontal and air resistance is assumed to be negligible, then its position after t seconds is given by the parametric equations x = (vo cos(a)t y = (vo sin(a)t - +- 1012 where g is the acceleration due to gravity (9.8 m/s2). (Round your answers to the nearest whole number.) (a) If a gun is fired with a = 30°...

A ball of mass 0.4 kg, initially at rest, is kicked directly toward a fence from a point 20 m away, as shown below. The velocity of the ball as it leaves the kicker’s foot is 16 m/s at angle of 46◦ above the horizontal. The top of the fence is 4 m high. The ball hits nothing while in flight and air resistance is negligible. The acceleration due to gravity is 9.8 m/s^2. Determine the time it takes for...
