Solve the all parts of given question:
Question: A small rubber ball is launched by compressed-air cannon from ground level with an initial speed of 11.8 m/s directly upward. Choose upward as the positive direction in your analysis.
Part A: What is the maximum height above the ground that the ball reaches?
Part B: How long does it take to reach the maximum height?
Part C: How long does it take to reach the ground after it reaches its highest point?
Part D: What is its velocity just before it hits the ground? (Indicate the direction with the sign of your answer.)
I need help to determine the maximum height above the ground that the ball reaches.
A high-speed lifting mechanism supports a 845-kg object with a steel cable that is 40.0 m long and 4.00 cm2 in cross-sectional area. (a) Determine the elongation of the cable. mm
A sample containing beryllium (atomic mass 9 u), aluminum (27 u), and an unknown element is placed in a mass spectrometer. Identify the element, using its chemical symbol
If you lie on the ground at night with no cover, you get cold rather quickly. Much of this is due to energy loss by radiation. At night in a dry climate, Estimate the net rate at which your body loses energy by radiation to the night sky under thes..
Light from a laser strikes a diffraction grating that has 6000 grooves per centimetre. The distance among the central maximum and the first order principal maximum is .7m on a wall that is 1.8m from the diffraction grating. Decide the wavelength of t..
Let's say your can has covers a distance of 3 m in 5 seconds under constant acceleration. Use kinematics equations and Newton's second law to calculate the acceleration of the can
A wedding ring (of diameter 1.89 cm) is tossed into the air and given a spin, resulting in an angular velocity of 16.9 rotations per second. find the maximum induced potential difference in the ring
A spring is used to propel a 0.400-kg hockey puck across level (frictionless) ice that becomes a rough (not frictionless) ramp inclined at 27°. If the puck reaches a maximum vertical height of 14 cm on the ramp, what distance does it travel along t..
The drawing shows a circus clown who weighs 725 N. The coefficient of static friction between the clown's feet and the ground is 0.51. He pulls vertically downward on a rope that passes around three pulleys and is tied around his feet. What is the mi..
