The fiugure below shows a birds eye view of ta car going around a highway curve

An archer fires an arrow straight up into the air with a speed 32

For a given initial projectile speed Vo, calculate what launch angle A gives the longest range R. Show your work, don't just quote a number.

A minisplit has a cooling capacity of 1200 BTU. How many kcal is equivalent?

Which is a hypothesis? A.) Clouds are observed in the sky. B.) You can relate the shape of a cloud to other objects, C). Why do clouds produce rain? D.) Clouds are made of water droplets.

The chart shows masses and velocities of four objects. Which lists the objects in order, from least to greatest momentum? Answer Y, W, X, Z

Try this out. Use a calculator! We can use the formula KE=0.5m*V^2. To find the kinetic energy (KE) of a payload of mass (m) 100 kg as it flies through the air at the velocity (v) of 55 m/s. (Multiply 0.5 x the mass x velocity squared.

Which group of measurements is the most precise? A) 2 g, 3 g, 4 g B) 2 g, 2.5 g, 3 g C) 2.0 g, 3.0 g, 4.0 g, 5.0 g D) 2.0 g, 3.0 g, 4.0 g

A 946.4 kg (2083 lb) car is moving at 14.8 m / s (33.0 mph). Calculate the magnitude of its momentum.

How do the positions of the hot and cold water affect the speed of convection

A fan is to accelerate quiescent air to a velocity of 12.5 m/s at a rate of 9 m3/s. Determine the minimum power that must be supplied to the fan. Take the density of air to be 1.18 kg/m3.
