(25%) Problem 4: Consider two projectiles that can be shot upward by spring guns. Object A is made of solid aluminum and has a mass of 50 grams. Object B is made of cast iron and has a mass of 200 grams. For this problem, you may take the gravitational field strength to be g = 10 N/kg. A 14% Part (a) Masses A and B are both shot straight upward at the same time. Mass A is shot with...
6. An astronaut ona distant planet wants to determine its acceleration due to gravity. The astronaut throws a rock straight up with a velocity of +15 m/s and measures a time of 20.0 s before the rock returns to his hand. What is the acceleration (magnitude and direction) due to gravity on this planet? See Diagram below: 20.0s v,15 m/s Show your work below: 7. Problem using vectors: A sailboat sails for 1 hr at 4 km/hr (relative to the...
Can anyone explains all the answers? Two balls, A and B are thrown at the same angle above horizontal, but initial velocity of ball A is two times greater than initial velocity of ball B. Ignore air resistance. we can conclude that horizontal range covered by ball A is same as range covered by ball B twice the range covered by ball B four times the range covered by ball B. greater than horizontal range covered by ball b, but...
A spring-gun projects a small rock from the ground with speed v0 at an angle ?0 above the ground. You have been asked to determine v0. From the way the spring-gun is constructed, you know that to a good approximation v0 is independent of the launch angle. You go to a level, open field, select a launch angle, and measure the horizontal distance the rock travels. You use g = 9.80 m/s2 and ignore the small height of the end...
A small, spring-loaded cannon launches a tennis ball from level ground with an initial speed vi at an angle θi with the horizontal. The tennis ball lands a horizontal distance R from its launch point. The highest point the tennis ball reaches during its flight is a distance R/12 above the ground. In terms of R and g, find the following. (You may ignore air resistance.) (a) the time interval during which the tennis ball is in motion (b)the tennis...
Problem 4 the bounced ball before the bounce. An outfielder throws a baseball to his catcher in an attempt to throw out a runner at home plate. The ball bounces once before reaching the catcher. Assume the angle at which shown in the figure below, but that the ball's speed after the bounce is one-half of what is was (a) Assume the ball is always thrown with the same initial speed and ignore air l leaves the ground is the...
A 1 kg ball and a 10 kg ball are dropped from a height of 10 m at the same time. In the absence of air resistance, O the 10 kg ball will take 10 times the amount of time to reach the ground. O the two balls will hit the ground at the same time. 0 there is not enough information to determine which ball will hit the ground first. O the 10 kg ball will hit the ground...
Help these athletes out. A) Determine the vertical impulse required for a 49 kg high jumper to clear a height of 6 ft 8 in. Assume that the high jumper's center of mass starts at 3 ft 6 in and that his center of mass just clears the bar. (positive up) (include units with answer) B) A golfer playing on a level course hits a 43.0 g golf ball that leaves the tee at a 25° upward angle and hits...
A ball of mass 0.200 kg is thrown straight upward. It reaches a maximum height of 5.00 mm above the point where it left the thrower's hand. Air resistance acts on the ball as it rises. −9.80J 9.80J zero not enough information is given to calculate the answer Part A How much work was done on the ball by the force of gravity during the time from when it left the thrower's hand to when it reached its maximum height?...
