Up where the ISS (International Space Station) orbits at 387 km, even though they are weightless there still is an acceleration due to gravity. Calculate its value and what it is in respect to 8g at the Earth's surface.
Law of Gravitation- Find out an expression for the magnitude of the initial velocity that a projectile should possess in order to leave the earth when air friction is neglected. The gravitational constant for g is, G = 6.67428*10^-11 m^3 Kg^-1 s^-..

A soccer ball with mass 0.446 kg is initially moving with speed 1.40 m/s. Over what distance must the player's foot be in contact with the ball to increase the ball's speed to 6.40 m/s
A car is travelling at 26 m/s when the driver spots a large pothole in road a distance 34 m ahead. She at once applies her brakes. If her acceleration is -7.5 m/s2, does she manage to stop before reaching the pothole.
A block is hung by a string from the inside roof of a van. When the van goes straight ahead at a speed of 25 m/s, the block hangs vertically down. But when the van maintains this same speed around an unbanked curve (radius = 155 m), the block swings ..
