Q1. A hockey player makes a slap shot, exerting a constant force of 30.4 N on the hockey puck for 0.12 s. What is the magnitude of the impulse given to the puck?
Q2. A space shuttle is launched from rest. It takes 8.00s to reach 156km/h, and at the end of the first 1.00 min its speed is 1567 km/h.
assuming the acceleration is constant throughout each time interval (but not necessarily the same in both intervals), what distance does the shuttle travel during the interval from 7.00 s to 1.00 min?
What should be the least kinetic energy in electron volts
What is the mass of sculpture (in kg) assume that the local acceleration due to gravity is 9.80 m/s2.
A spring with spring constant 12.5 hangs from the ceiling. A 400 ball is attached to the spring and allowed to come to rest. It is then pulled down 6.80 and released. What is the time constant if the ball's amplitude has decreased to 3.90 after 57.0 ..
You are driving to grocery store at 15 m/s .You is 140 m from an intersection when the traffic light turns red. Suppose that your reaction time is 0.70 s. and that your car brakes with constant acceleration. How far are you from the intersection whil..
With what minimum speed should you toss a 140g ball straight up to hit the 11.0m-high roof of the gymnasium if you release the ball 1.30m above the ground? Resolve this problem using energy.
