1) An object undergoes uniformly accelerated motion from point x1 = 6 m at time t1 = 3 s to point x2 = 47 m at time t2 = 7 s. (The direction of motion of the object does not change.) (a) If the magnitude of the instantaneous velocity at t1 is v1 = 2 m/s, what is the instantaneous velocity v2 at time t2? (b) Determine the magnitude of the instantaneous acceleration of the object at time t2. 2)...

Question 1 (1 point) Cart e Sensor In lab you will roll a cart down a nearly frictionless incline set at a small angle (see image). The cart will start at rest and travel a set distance. After travelling, the flag will pass throu photogate in order to measure the speed. f (the speed at the end of the trip). From the time measured by the photogate you calculate the final velocity to be vf- 1.84 :0.09 m/s. What is...

Introduction: In this lab you will investigate the conservation of linear momentum: momentum before an event equals momentum after an event if there is an absence of a non-conservative forces such as friction. The event is this case is a collision between two air track gliders. Two types of collisions will be studied. One is an elastic collision which will not be studied in this lab. after the collision.

A device is created in the lab which measures the velocity of two carts on a track. The two carts are proving towards each other. Cart A is moving the right and Cart B is moving to the left. After an inelastic collision they are moving, stuck together, to the right. Momentum is conserved in this experiment. The equation relating the momentum to the mass and velocity is: p = mv where p is the momentum, m is...
