You throw a ball straight up at 45 m/s. how many seconds elapse before it is traveling downward at 9 m/s?

Which of the following are products of cellular respiration? Sunlight Oxygen ATP Water Carbon Dioxide

A spacecraft is traveling in interplanetary space at a constant velocity. What is the estimated distance traveled by the spacecraft in 9.50 seconds? A) 2.30*10^2 B) 2.42*10^2 C) 2.51*10^2 D) 3.02*10^2

There is little sunlight at high latitudes during the winter, so few crops can grow even if temperatures are regulated. To address this problem, special lamps can be used in greenhouses. These lamps allow plants to grow during the winter months.

A sinusoidal electromagnetic wave has a peak electric field of 8.00 kv/m. what is the intensity of the wave? (c = 3.0 * 108 m/s, μ0=4π * 10-7 t • m/a, ε0 = 8.85 * 10-12 c2/n • m2)

The acceleration of gravity is 9.8 m/s 2. After impact, the block slides 9.15 m before coming to rest. 84 g 10.4 g vbullet 94.4 g 9.15 m µ = 0.251 If the coefficient of friction between block and surface is 0.

A car is moving with a velocity (3.0 m/s) € x ˆ + (1.0 m/s) € y ˆ and 3.0 seconds later its velocity is (6.0 m/s) € x ˆ - (3.0 m/s) € y ˆ. What is the direction of the average acceleration of the car?

When water vapor condenses on the inside of a window, the window becomes

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.
