(Using the equation mv=Ft, if F is doubled, 2F, and m is unchanged, then over the same time, t, the speed is 2v) If the mass of a rocket is doubled, but not the amount of time the engines were fired, the speed would be. If the rocket used two thrusters to double the force, then the speed would be. Force from each scale is one-half your weight) A rocket is moving through space on one thruster. Forces from both scales add to cancel your weight. (Acceleration=net force/mass) When you stand on two bathroom scales with one foot on each scale and with your weight evenly distributed, each scale will read. If the force remains the same while the mass of the cart decreases to half, the acceleration of the cart. Consider a cart pushed along a track with a certain force. Both accelerating at 1N/kg=1m/s/s A cart is pulled to the right with a force of 15N while being pulled to the left with a force of 20N. Which, if either, has the greater acceleration? Calculate both accelerations. Shopping cart B is 20kg and is pulled with a force of 20N.
(The horizontal component is drag.)) Shopping cart A is 10kg and is pulled with a force of 10N. The vertical component of this is upward lift. (When a wing diverts air downward, it exerts a downward force on the air the air simultaneously exerts an upward force on the wing. Slightly tilted wings of an airplane deflect. Neither vehicle feels a greater force on it by the other. A large bus collides "head-on" with a small car. (Inertia is a property of matter, not a reason for the behaviour of matter). The use of inclined planes for Galileo's experiments helped him to. (As upward forced of air resistance increases, the net force decreases). More than 35 m/s As a skydiver continues to fall faster and faster through the air, her acceleration. Exactly 1 second later, its speed will be.
