You fire a projectile at an angle along flat ground, giving it an initial horizontal velocity of 8.43 m/s and an initial vertical
velocity of 7.07 m/s.
(the resulting initial speed is vo = 11 m/s at an angle of
00 40 degrees above the horizontal)
How long is the projectile in the air? 1
=
х
S
What is the projectile's speed as it passes through the highest
point in its trajectory? -11
x m/s

A1,700kg car is being used to give a 1,400kg car a push start by exerting a force of 140n the impulse on the smaller car during the 30.0s of contact is +670kg*m/s. what is the impulse of the smaller car on the larger car? -814 kg*m/s 0kg *m/s -670kg*m/s -550kg*m/s
