A 62 kg driver gets into an empty taptap to start the day's work. The springs compress 2.1×10−2 m. After driving a portion of the route, the taptap is fully loaded with a total of 25 people including the driver, with an average mass of 62 kg per person. In addition, there are three 15-kg goats, five 3-kg chickens, and a total of 25 kg of bananas on their way to the market. Assume that the springs have somehow not yet compressed to their maximum amount. How much are the springs compressed?
A vehicle with a mass of 2754.49 kg is being tested for its engine consumption by measuring the force it needs to move the vehicle upon covering a certain distance.

The net force is 6711 N. Answer with illustration.
A 200 g rubber ball is tied to a 1 meter long string and released from rest at an angle theta. It swings down and at the verybottom has a perfectly elastic collision with a 1 kg block. The block is resting on a frictionless surface and is connected to a 20-cm long spring with (k = 2000 N/m). After the collision, the spring compresses a maximum distance of 2 cm. From what angle was the rubber ball released? Draw any force diagrams to support your answer.
A reckless car driver is traveling 50 m/s north in rainy weather. The car driver decides to run a stop sign and collides with a truck driver who is traveling 15 m/s northeast. The car has a mass of 2,000 kg and the truck has a mass of 20,000 kg. Assuming the collision is perfectly inelastic and the friction of the road is negligible due to the wet weather, determine the final velocity and direction of both vehicles. Determine the percent change in kinetic energy of the system using the formula, (|Kf-Ki|/ Ki)*100% where subscripts “i” and “f” denote initial and final, respectively.
