The parking brake on a 1000 kg Cadillac has failed, and it is rolling slowly, at 1 mph, toward a group of small children. Seeing the situation, you realize you have just enough time to drive your 2000 kg Volkswagen head-on into the Cadillac and save the children. Part A With what speed should you impact the Cadillac to bring it to a halt? Express your answer in miles per hour.

You are playing a game and you push a cart to give it in. speed. The cart starts at the bottom (zero) of a ramp and after reaching the top of the ramp, the cart travels across a horizontal track w/ friction. The mass of the cart is 44 x 10^-3 kg. The ramp is 56 cm high. The length is 70 cm. What can you infer of the intial speed in (m/s)
The heaviest watermelon weighed in at 159 kg (350.5 lbs.) and was grown by Chris Kent (USA) of Sevierville, Tennessee. Chris releases the watermelon from rest from the top of a 150.0m tall building by a small crane. We neglect air resistance. If needed, use 9.80 m/s2 for the magnitude of g. What is the time it takes to hit the ground after being released and what will be the final impact velocity when it hits the ground? Report answers to 3 sig figs.

Sam, whose mass is 74.0 kg, takes off across level snow on his jet-powered skis. The skis have a thrust of 220.0 N and a coefficient of kinetic friction wtih the snow of 0.07. Unfortunately, the skis run out of fuel after only 11.5 seconds. What Sam's top speed (in m/s) assuming that the acceleration due to gravity is 9.80 m/s2? How far (in m) has Sam traveled when he finally coasts to a stop?
A 50-kg cart is rolling across the floor with an initial speed of 4 m/s toward a glass window which is 5 m away. Unless you push against the cart to help stop the cart will not stop in time to keep from rolling into the window. The coefficient of friction against the cart is 0.15. You step in front of the cart and push against the motion. You will find what force you need to push in order to stop the cart in a distance of 5 m. what is the net force? what is the force of friction on the cart? what is the force of the push?
Spring Gun: Planet X was just discovered orbiting a nearby star! It orbits a start that is 6.9 times the mass of our sun in a solar system just 31.3 light-years away. The acceleration due to gravity there is 0.07 g. After making some measurements in lab, you start to daydream about travel to other planets. Your spring gun can launch a projectile with a speed of 3.7 m/s. What would happen if you were to launch a projectile at an angle of 32 ° above horizontal on Planet X? (a) What maximum height would the projectile reach? (b) How far would the projectile travel before it hit the ground? Assume the projectile lands at the same height it was launched from.
A clever coyote uses rocket powered skates to try to catch a roadrunner. The mass of the coyote is 38.1 kg. If the coyote starts from rest, and accelerates to a final speed of 26 m/s in a distance of 2.4 m, how much thrust force did the rockets excert to get him to his final speed? Assume this thrust is constant over the 2.4 m.
A small rocket for gathering weather data has a mass of 30 kg and generates 1500 N of thrust. On a windy day, the wind exerts a 20 N horizontal force on the rocket. If the rocket is launched straight up, what is the shape of its trajectory, and by how much has it been deflected sideways when it reaches a height of 1.0 km? Because the rocket goes much higher than this, assume there’s no significant mass loss during the first 1.0 km of flight.
