Q1. A plane leaves the airport in Galisto and flies 145 at 68 east of north and then changes direction to fly 225 at 48 south of east, after which it makes an immediate emergency landing in a pasture.
When the airport sends out a rescue crew, how far should this crew fly to go straight to this plane?
Q2. A vertical container with base area measuring 16 cm by 18 cm is being filled with identical pieces of candy, each with a volume of 50 mm3 and a mass of 0.020g. Suppose that the volume of the empty spaces between candies is negligible. If the height of the candies in the container increases at the rate of 0.230cm/s, at what rate (kilograms per minute) does the mass of the candies in container increase?
A bus is traveling up a hill at a speed of 34m/s. The hill is 23 degrees relative to horizontal and the coefficient of static friction between the bus's tires and the road is 0.6. What is the car's minimum breaking distance?

Estimate the gravitational force between the Sun and Venus. The mass of the Sun is 1.99×10^30 kg. The mass of Venus is 48.7×10^23 kg. The distance between them is 10.8×10^10 m.
An airplane is flying with a velocity of 89.0 at an angle of 18.0 above the horizontal. When the plane is the distance 112 directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from the dog wo..
When Babe Ruth hit a homer over the 7.5 -high right-field fence 98 from home plate, roughly what was the minimum speed of the ball when it left the bat? Assume the ball was hit 1.4 above the ground and its path initially made a 37 angle with the grou..
Charge A and charge B are 2.5 m apart. Charge A is 1.4C and charge B is 2.5C. Charge C, which is 2.0 C, is situated between them and force on charge C is zero. How far from charge A is Charge C.
Find out that the value of the gravitational field strength
The tape is now wound back into the drum at angular rate. With what speed would the end of the tape move? (Note that our drawing specifies that a positive derivative of implies motion away from the drum. Be careful with your signs. The fact that the ..
A rifle fires a 2.39 10-2-kg pellet straight upward, since the pellet rests on a compressed spring that is released when the trigger is pulled. The spring has a negligible mass and is compressed by 9.17 10-2 m from its unstrained length. The pellet r..
