Q1. A 0.135 kg ball is thrown straight up from 1.94 m above the ground. Its initial vertical speed is 12.00 m/s. A short time later, it hits the ground. Compute the total work done by the force of gravity during that time.
Q2. The radius of the tires on your car is 0.33m. You drive 1400 m in a straight line. What is the angular displacement of a point on the outer rim of a tire, around the center of tire, during this trip? Suppose the tire rotates in the counter clockwise direction.
A race car has a mass of 718 kg. It starts from rest and travels 45.0 m in 3.0 s. The car is uniformly accelerated throughout the entire time. What net force is exerted on it.

What is the maximum speed with which a 1200- car can round a turn of radius 71 on a flat road if coefficient of static friction between tires and road is 0.45.
A baseball is bunted down the third-base line leaving the bat from a height of 0.850m with an initial velocity of 4.00m/s at an angle of 37.87° above horizontal.
How many 104 W lightbulbs can you use in a 102 V circuit without tripping a 17 A circuit breaker? (The bulbs are connected in parallel that means that the potential difference across each lightbulb is 102 V.)
