A 10-g penny is dropped from a building that is 125 m high. The penny is initially at rest. Approximately how long does it take the penny to hit the ground?
A mouse, escaping from a cat, moves with an initial velocity of 1.5 m/s [W], and then accelerates at 1.8 m/s² [E] for 6.0 s. Calculate
1. A kick that lasts 0.03s sends a ball of mass 0.65kg with a velocity of 15m/s northwards find the displacement of the ball in 2 seconds given the upward acceleration of the ball is 2m/s²
At t = 0, an object is at a position of -12 meters of a one-dimensional coordinate system and is moving in the positive direction at 5 m/s.It constantly gains velocity at a rate of +2 m/s each and every second
A boy drops a stone from a cliff and counts the seconds until the stone hits the base. He counts 3 s. About how high is the cliff.
A car uniformly accelerates from rest at 3.0 m/s2 down a 150-m track. What is the car's final velocity?
A police officer finds 60 m of skid marks at the scene of a car crash. Assuming a uniform deceleration of 7.5 m/s2 to a stop, what was the velocity of the car when it started skidding?
In an electron gun of a television set an electron with initial speed of 10 cube metre per second enters a region where it is electrically accelerated.it emerges out of this region after 1 microsecond with speed of 4×10 m/s. What is the maximum length of
A boy is riding a bicycle at a velocity of 5.0 m/s. He applies the brakes and uniformly decelerates to a stop at a rate of 2.5 m/s2. How long does it take for the bicycle to stop?
On an airless planet, an astronaut drops a hammer from rest at a height of 15 m. The hammer hits the ground in 1 s. What is the acceleration due to the gravity on this planet?
