questions please help!?
An archer shoots an arrow toward a target of 300 g that slips in your direction at a speed of 2.30 m / s in one, slippery smooth surface. The 22.5 g arrow is fired with a speed of 35.0 m / s, and passes through the target, which is held by the impact. What is the speed the arrow after passing through the goal? 2) high-speed stroboscopic photographs show that the head of a Golf Club 250 g moving at 40 m / s just before hit a golf ball 46 g resting on a tee. After the impact, the clubhead travels (in the same direction) to 33 m / s. Find the speed of the ball course right after impact. 3) Two cars of equal mass approach an intersection. A vehicle traveling at a speed 14.0 m / s to the east and the other to the v2i speed north. Neither the driver sees the other. The vehicles collided at the intersection and was hit, leaving parallel drag marks at an angle of 57.0 ° north of east. What was the initial velocity of the vehicle moving north?
You're more likely to get answers if they separate issues.
