A projectile has an initial velocity of 7 m/s at 35 above the horizontal. Which equation correctly gives the y-component of this velocity? a) Vy = (7 m/s) cos (35) b) Vy = (7m/s) sin (35) C) Vy= (7m/s)/ cos (35) d) Vy = (7 m/s)/ sin (35) e) Vy = sin (35) / (7 m/s)

A car is driving east. It experiences a brief acceleration pointing 45 west of south. This causes the car to a) speed up only b) slow down only c) turn only d) speed up and turn e) slow down and turn
