a) Using the distance-versus-time graph below, determine the instantaneous speed of the bicycle at 4 hours.b) Explain the relationship between the speed and steepness of the slope of the line on the distance-versus-time graph. How to find constant velocity Co...
A ball thrown up reaches a height of 0.50 m. How high up will the same ball reach if it is being thrown up with twice the initial speed? A ball is equipped with a speedometer and launched upward. The speedometer reading three seconds after launch; the ball is movin...
An open lift is coming down from the top of building at a constant speedv=10m/s. A boy standing on the lift throws a stone vertically upwards at a speed of 30 m/s w.r.t. himself. The time after which he will catch the stone is: ...
A ball is thrown directly downward with an initial speed of 7.20 m/s from a height of 29.9 m. After what time interval does it strike the ground? A child on a bridge throws a rock straight down. The rock leaves the child's hand at t...
If a ball is thrown horizontally at this speed, how much will it drop by the time it reaches a catcher who is 17 m away from the point of release? Explain the steps to calculate final velocity when many masses collide? A jogger runs 6.0 km E, then 4.0 km N, and finally 2.0 km ...
