At which value of t will the cart be back at the starting point
Netgear lb1120 hack
Mar 27, 2016 · Assuming no air restance the speed when the ball comes back to the starting point will be again #8m/s# but directed DOWNWARDS; we can express this saying that it will equal to #-8m/s# adding a minus to indicate the downward direction. To find the time of flight we use: #v_f=v_i+at# Where: #a# is the acceleration of gravity (downwards, #-9.8m/(s ...
The car is traveling in the -x-direction and it is speeding up. A small cart is rolling freely on an inclined ramp with a constant acceleration of 0.50 m/s in the -x-direction. At time t=0, the cart has a velocity of 2.0 m/s in the +x-direction.
